Which equation has a graph that is parallel to the graph of 2x - y = - 1?

A. 2x + y = 8

о В.

y=-x+3

O C. y-1 = 2 (x - 3)

O D. y = - 2x - 1

The answer is C) y-1=2 (x-3)

Step-by-step explanation:

Two equations are parallel if they have the same slope and different y-intercepts. In the answer (c) 2 represents the slope which is also the slope of the original equation. y=2x-5is the equation that you get when you distibute and isolate y.

C.

Step-by-step explanation:

Parallel lines have the same slope but different y-int. So if our original equation is y = 2x + 1, then the other equation would have to be y = 2x + b, where b ≠ 1. Only answer C. works.
