Graph 2x-3y=18

please help me with this​

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

Find the equation of the ellipse with the following properties. the ellipse with foci at (0, 6) and (0, -6); y-intercepts (0, 8) and (0, -8).edit: the answer is x^2 over 28 + y^2 over 64 = 1

Change negative exponents to positive, then solve
