Verified answer

a.y = -x - 5

I got that answer by having prior knowledge that parallel lines have the same slope. So therefore I used the rise over run formula, which is -5-1/2--4. I then got -6/6 after simplifying it, which is also -1. Since answer a is the only equation containing -1 as the slope,answer a is therefore the answer.

Hope I helped:D

The slope of the line is:

(1 - (-5))/(-4 - 2) = 6/-6 = -1

Parallel lines have the same slope.

The only equation given with a slope of -1 is (a).
