Answer:

y = - 0.2x + 6.8

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes

Given line

y = 5x - 15

Perpendicular line is

y = - 1/5x + b

Using given point (-6, 8), finding y-intercept

8 = - 1/5*(-6) + b
8 = 6/5 + b
b + 1/2 = 8
b = 8 - 1.2
b = 6.8

So the line is

y = - 0.2x + 6.8
