What's the slop of the line whose equation is 87 = 7 - 2y?

This is similar to the other one where i posted. You subtract 7 from both sides so the equation will be 80= -2y. Then divide both sides by -2, and the equation will be y=-40. This is a straight line so the slope is zero. If there are no x's in your equation, the slope will always be zero.
