Answer:
Since the Line is Perpendicular
m.m'=-1 
The line 
y=x+8
Comparing with 
Y=mx + C
m=1
m.m'=-1 
m'=-1/m = -1/1 = -1. 
y-y' = m'(x-x')
The point it passes is (-7,8)
y-8= -1(x--7)
y-8=-1(x+7)
y-8 = -x - 7 
y + x -1 = 0.
or In Slope intercept Form
Just Make y the subject 
y= -x + 1 ..... This is your answer.
Hope this helps!!!
 
        
             
        
        
        
Answer:
1/3
Step-by-step explanation:
Slope is rise over run.
Pick a point and count how many steps up and how many steps to the right you need to make to get to the next point. That's how you find slope.
