Question

Write an equation for the line that is parallel to y = −2x and passes through the point (0, −7).

A) y = 2x + 7
B) y = 2x − 7
C) y = −2x + 7
D) y = −2x − 7

Answer 1

D) y = -2x − 7

Explanation:

Parallel lines have the same slope, so m = -2.

The y-intercept is (0, -7), so b = -7.

Therefore, the line is y = -2x − 7.

Answer 2

Input the equation into Desmos. It’s really useful for graph stuff and does the work for you
