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: $y - y_1 = m (x - x_1)$,

Related concepts: Parallel and perpendicular lines in linear functions, System of linear equations, Graphing linear inequalities in two variables, Graphing systems of linear inequalities,
