Question

Write an equation of the line passing through the point A(–1,5) that is perpendicular to the line y = 1/7x+4

Answer 1

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!
