Answer:
-7x - 2
Step-by-step explanation:
First, find the new slope that is perpendicular.
1/7 -> 7 -> -7
So far, we have -7x + b. (we use mx + b)
Since you asked for it to pass point A (-1, 5), substitute in x and y.
y = -7x + b
5 = -7(-1) +b
5 = 7 + b
b = -2
So the equation would be -7x - 2.
Your welcome!
