ALGEBRA 1 QUESTION!!! HELP ME! DUE TOMMOROW?

1. The axis of symmetry is y=1. If you were to graph a parabola with x intercepts at -3 and 5, then draw a line down the center of that parabola where both sides would be equal (symmetrical), that line would be at y=1, because 1 is halfway between -3 and 5.
