If 2 lines are perpendicular to each other then the product of their gradients is equal to -1 .
If gradients of 2 perpendicular lines are m 1 and m 2
then: m 1 × m 2 = - 1
The equation y = 1 8 x + 7
is of the form y = mx + c , where m represents the gradient and c , the y-intercept.
hence this line has m = 1 8
m of perpendicular is found using the above relationship.
1 8 × m 2 = - 1 m 2 = - 1 1 8 = - 8
