(Points : 1)

A. y=-7/5x-7/10

B. y=5/7x+10/5

C. 5/7x-10/7

D. y=-5x-7

Answer 1

to isolate y first step as follows;

5x - 7y - 10
-7y = -5x -10 (change the 5x to this side as negative)

Answer 2

why are you changing it to a negative?

Answer 3

then divide by -7 and you have

-7y = -5x + 10
--- --- ---
-7 -7 -7

then you havd:

y = 5/7x -10/7
