Thus;

The slope of our first line is m =
2
Thus
-45-6X
5
Perpendicular lines have negative reciprocal slopes
Thus; negative reciprocal of
10 =
(20) +b
: 10 = 100 + b

5 is slope of our line
The equation of line passing through point (20, 10).
So substitute given points in equation y= 5x +b -0
b = 10-100

put value of 'b' in 1 we get; y = 5x-20
6Y = 5X-40
