Question

A line passes through the point (–1,–2) and is perpendicular to the line with the equation y = –x – 1. What's the equation of the line?

Question 8 options:

A)

y = x – 1

B)

y = –x + 3

C)

y = –x + 7

D)

y = x – 5

Answer 1

A) y = x - 1

Explanation:

First, solve for the new slope by taking the opposite reciprocal, and you will get:

1

Then, solve for the equation in point-slope form:

y+2 = 1(x+1) or just y+2 = x+1

Last, solve for y on one side:

y = x-1
