First, we need to find the slope of the line passing through
If we multiply the slope of any line with

slope = -8
Explanation:
The first step is to calculate the gradient ( slope) of the line passing through the 2 given points using the
color(blue)" gradient formula "
m = (y_2 - y_1)/(x_2 - x_1) where
(x_1,y_1)" and " (x_2,y_2)" are 2 coordinate points " let
(x_1,y_1)=(-6,17)" and " (x_2,y_2)=(2,18)
rArr m = (18-17)/(2-(-6)) = 1/8 If 2 lines with gradients , say
m_1" and " m_2" are perpendicular" Then
m_1 xx m_2 = -1
rArr 1/8xxm_2 = -1 rArr m_2 =-1/(1/8) = -8
