👉 Learn how to write the equation of a line that is perpendicular to a given line. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e., there are no exponents in ...
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 ...
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 ...
