Perpendicular line equation

Topic Notes

In this lesson, we will look at questions related to perpendicular line equation. We will try to determine perpendicular line equation with different given information such as, graphs, equations of other lines and points.

Basic Concepts

Slope equation: $m = \frac{y_2-y_1}{x_2- x_1}$
Slope intercept form: y = mx + b
General form: Ax + By + C = 0
Point-slope form: $y - y_1 = m (x - x_1)$
