7x - 4x + 9 > 18 what's the answer?

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

Which graph represents the parent function of y=(x+2)(x-2)

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)
