Icannot seem to figure out how to solve this

Name these type of angles shown check all that applies

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

Find the value of x for which line a is parallel to line b
