Perpendicular lines will always cross at right angles. To determine if two lines are perpendicular, we need to multiply their gradients together. If the lines are perpendicular to each other, the ...
When two lines are perpendicular, the product of their gradients is 1. Lines A and B are perpendicular. A line L₁ has the equation \(3y = 2x - 5\).What is the equation of the line L₂ which ...
