The parallel and perpendicular line calculator finds equations for a parallel and perpendicular line that passes from a specific point and also shows their graphic representation. Explore more by reading on!
“Parallel lines are lines that do not intersect each other and on the other hand, perpendicular lines are two lines that intersect each other at 90 angle”.
By using a parallel line calculator you can find the equation of a line that passes through a point. Hence, here take a quick look at their attributes.
To find the parallel and perpendicular lines first keep in view the following formula:
Y = ax + b
Where:
An online perpendicular slope calculator plots an equation that passes from a certain point or gradient between two points in the Cartesian coordinate plane.
If there are two lines “a” and “m” that are perpendicular to each other then the product of slopes is -1. As we already know the line of the equation proves the slope of perpendicular lines.
a * m = -1
a = -1 / m
Insert this in the line equation y = ax + b
y = -1/m . x + b
b = y + 1 / m . x
This is the coefficient b which is also known as the y-intercept
By using the parallel and perpendicular line calculator find the slope If there are two lines that are parallel to each other. As we know the equation:
Y = ax + b
When you plug in the coordinates (xj,yj) and a = m then the equation line will be:
Yj = m . xj + b
Suppose a line is passing through a point (-13, 3) and parallel to y = 2x - 6. Find out the parallel and perpendicular lines equations by perpendicular line equation calculator.
Given Data:
Slope-intercept of the equation of a line is: y = 2x - 6y
The parallel line of the slope is the same: m = 2
So, the parallel line equation is y = 2x + a
To find a, the line should pass through a given point:
3 = (2) * (-13) + a
a = 3 + 26
a = 29
Consequently, the equation of the line is y = 2x +29
Suppose that the same line passes from points (-10, 3) but is perpendicular at y = 4x + 3. Find their slope-intercept form.
The slope-intercept of the equation of a line is y = 4x + 3
The slope of the perpendicular line is referred to as a negative inverse m = -1 / 4
So, the perpendicular line equation is y = -1 / 4x + a
To find a, the line should pass through a given point:
3 = -1 / 4 * (-10) + a
a = 1 / 2
Consequently, the equation of the line is y = 1 / 2 - x / 4
The perpendicular calculator allows you to find the equation for parallel and perpendicular lines fast and accurately! Providing the following values is required to make it work:

Our slopes of parallel and perpendicular lines calculator gives you the following results:
Perpendicular lines do not have the same slope. Their slopes are different from one another.
Perpendicular lines have negative reciprocal slopes because when there are two lines that are perpendicular to each other it is almost as the rise as run switched places therefore one line has an opposite reciprocal slope to the other perpendicular line.
A “parallelogram” is a shape that has four pairs of parallel lines.
A line with a zero slope is flat in the horizontal direction and it means there is no change in the x and y coordinates
