What is the equation of the trend line in the scatter plot ?

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

The longer leg of a 30-60-90 trangle is 18

Which statement best describes how to determine whether f(x) = x squared- x +8 is an even function ?
