How to Use the Perpendicular Line Calculator?The procedure to use the perpendicular line calculator is as follows: Step 1: Enter the line equation and the coordinates of a point by which the line passes through, in the input field Step 2: Now click the button “Calculate Perpendicular Line” to get the equation Step 3: Finally, the perpendicular line equation will be displayed in the output field What is Meant by the Perpendicular Line?In mathematics, the perpendicular lines are the lines in which they intersect at right angles (i.e., 90 degrees). In other words, a line is said to be a perpendicular line, when one line meets another line at 90 degrees. For example, the adjacent sides of the rectangle and square remain perpendicular to each other. In case, if two lines are perpendicular to the same line, then that two lines are parallel to each other and those lines will never intersect. Once you know the equation of the new line, finding the intersection point between it and the first (given) line is a straightforward task. All you have to do is find a point with coordinates (xₐ,yₐ) such that it lies on each of the two lines. Consider the example we've just analyzed. We found two perpendicular lines: Let's solve this system of equations:
Multiplying the second equation by 4, you get
Adding the two equations together,
From there,
The coordinates of the point of intersection are (3.4, 4.8). Of course, you don't have to carry out these tedious calculations all by yourself - our perpendicular line calculator can do the same in just a few seconds! And don't forget to check our other coordinate geometry calculators like the average rate of change (aroc) calculator. The equation of a line calculator illustrates the vertical change divided by the horizontal change along with graphical illustrations. We also describe it as the rise over the run change in the Cartesian coordinates. So let’s move on to know more about the line equation and its determination scenario! Stay Focused! What is the Equation of a Line?The equation of a line in an algebraic form represents the set of points that together form a line in a coordinate system. Many points join together represented as a complete line and we are only finding two points to draw a line in the Cartesian coordinates.  Types of Equation of Line:There are 3 common types of the Equation of line with a slope. We can find the equation of a line in its general forms and their corresponding relationship with these line equations as given below:
Point Slope Form:The general equation in the point-slope form can be written as: Point Slope Form: In the point-slope form, we only need only one point ( x1,y1) to find the equation of a line in
point-slope form. We can be defined in the equation of a line that passes through two points in the above-mentioned calculators. The point-slope calculator is best to unveil and draw the equation of the line. Slope Intercept Form:The Slope-Intercept Form can be written in the form: Slope Intercept Calculators are just too useful in finding the Slope-Intercept Form. Standard Form:The Standard Form of the equation for a line can be written as: Ax + By = C We can also write the standard like this also: Ax + By + C = 0 Where A, and B are the coefficient of the variables x, y “C” is the Y-intercept of the line. The Standard Form of the equation can be illustrated well by the Standard Form Calculator. The Examples of All Form of Equation of line:We unveil the whole concept of the Equation of line by depicting the practical examples of the Point slope form, Slope intercepts form and the Standards form respectively. Example of Point Slope Form:Let’s consider one point each along the x-axis and y-axis (3,5) and the slope “m” is equal to 6. We can write an equation of the line that passes through points(3,5) and has a slope “6”. We know how to find the equation of a line Point Slope Form, so it can be simple how to find the equation of a line with one point and slope? y – y1 = m(x – x1) Putting the values in the equation of the line in Point Slope Form: y – 5= 6(x – 3) This is the equation of the line in the Point-Slope Form: Example of Slope-Intercept Form:Now consider the slope of the line “m” is 6 and the y-intercept “c” is 8. Then the equation of the line in the Slope-Intercept Form: y = mx + c Putting the values in the Slope-Intercept Form equation, we get: y= 6x+8 Slope Intercept Form is just o easy to find by equation of a line calculator Example of Standard Form:You can use the point-slope form or slope intercept form equation to convert it into the Standard Form: You should be aware we can’t use the fractions or decimals as the coefficient of the “x”. It means the coefficient of the “x” should be just positive: Take the Slope intercept form: y= 6x+8 Now we apply the operation: ⇒ 6x+8-y=0 ⇒ 6x-y+8=0 The Standard Form is as follows: 6x-y=-8 How to Find the y-Intercept of line Equation:We can find the y-intercept when x=0, it is a point where the line crosses the y-axis. Now insert the values in the equation of a line calculator, we find the values: y = 3x – 7 Using the equation y = 3x – 6, keep x=0, to find the y-intercept: y = 3(0) – 7 y= -7 The y-intercept is “-7”. How to Find the X-Intercept of line Equation:The x-intercept of a line is the value of x when y=0. It is the point where the line crosses the x axis of the cartesian coordinates. We can write an equation of the line that passes through the points y=0 as follows: Using the equation: y = 3x – 6, put y=0 To find the x-intercept. 0 = 3x – 6 3x = 6 The x-intercept is 2 of the slope-intercept form of line equation is: x = 2 The slope of the Parallel lines:When we are finding the slope of one line then there will be the same values of the parallel line as they have the same values of “m”. So they never intersect with each other. The slope of Perpendicular Lines:Perpendicular lines will have a slope equal to the negative inverse of the known slope. We can find an equation of the line which is perpendicular to the other. These lines from a 90° angle when they intersect. We are able to find the slopes perpendicular to each other by the equation of a line calculator. How to Find the Equation of a Line Perpendicular to Others?Consider a line with a
slope of -5.
The equation of a line that passes through two points and is perpendicular to each other has slope “5” and ⅕ respectively. Working on the Equation of a Line Calculator:You can find the equation of the line point-slope form, slope-intercept form and standard form additionally we are able to find the equation of a line with two points on the Cartesian coordinates. Input:
Output: The line equation from two points calculator unveils through some solution of all the forms of the equation of the line. The graphical representation depicts us to understand the whole concept easily.
FAQs:How do you graph the equation of a line?You can graph an equation by finding the y-intercept = c of the equation y = mx + b and slope of line. What is the Y-intercept of the straight line?It is a point where the straight line cuts down the y-axis, and x=0, when y=mx+c. Then c is the y-intercept of the equation. Conclusion:Linear equations are very important in mathematical and everyday applications. We are able to describe the relationship between two variables to predict, calculate the rate, and define the relationship between two quantities. The equation of a line calculator depicts the whole process of drawing the equation of the line.

Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.
