Please find mA and mB please.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Can someone me with these two circle theorem questions asap?

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