How much?Pls help me.

With #! i’ve tried to figure it out but i can’t.

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

Give me the equations of two lines that have the same slope but are not parallel.
