The polynomial a - 2b + 3c is a linear polynomial. Please answer if correct or not and explanation please ​

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

If 25% of y is 30, what is 60% of y?
