When two lines are perpendicular, the product of their gradients is -1. The two lines are perpendicular. Line A \(m = 2\) Line B \(m = - \frac{1}{2}\) A line L₁ has the equation \(3y = 2x - 5\).What ...

Higher - The gradients of two perpendicular lines will always multiply to make –1. Make sure you are familiar with finding the equation of a line and calculating gradient to understand equations of ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
