Question 508298
The graph of f passes through (-3,7) and is perpendicular to the line that has an x-intercept of 7 and a y-intercept of -56. 
---
Find slope of line thru (7,0) and (0,-56)
slope = (-56-0)/(0-7) = 8
------
Any line perpendicular to that line must have slope = -1/8
----
Find equation of line with slope = -1/8 and passes thru (-3,7).
Form: y = mx + b
7 = (-1/8)(-3) + b
7 = (3/8) + b
b = (56/8)-(3/8)
b = 53/8
---
Equation:
y = (-1/8)x + (53/8)
