Solve -4x - 10 = -2y for y. put your answer in the form y=mx+b with no spaces. y=2x+5 y=-2x-5 y=-2x+5 y=2x-5

To solve for y you have to get y by itself. To do that, you use inverse operations. The inverse of addition is subtraction and inverse of multiplication is division. 

-4x - 10 = -2y   Divide by -2 to get y alone. What you do to one side of the
    ÷-2       ÷-2    equation, you must do to the other. 
-2x - 5 = y

So the answer is b, y=-2x-5
