-7x+7y=-28
-3x-4y=-12

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Solve the equation by completing the square. x^2+2x=17
