5y^2-2y-7=0
Product(x)= -35
Addition(+)= -2
~=5 and -7
5y^2+5y-7y-7=0
5y(y+1)-7(y+1)=0
(5y-7) (y+1)

Answer:
<h2>
Its C. y = 1/4x</h2>
Step-by-step explanation:
Look at the line. See where it attaches at one point and look where it attaches to another, for example, in this expression, it attaches to (0,0) and (4,-1). Then do rise over run, or y over x. This means to do this- y2 - y1 divided by x2 - x1. First, do -1 - 0. Its a double negative, so it becomes positive, thus making it 1 - 0, which is still 1. Then do 4 - 0, which is still 4. Divide 1 by 4, turn it to a fraction, and boom, you've got 1/4x.
Hope this helps!!!!![?][?][?]
