PLZ help explain how to graph the inequality 8≥y

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

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
