help pls

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1

40 points which is the equation of a line perpendicular to the line with the equation: y = 1/4x + 2 a : y = -4x - 7 b : y = 4x + 2 c : y = 1/4x - 1/2 d : y = -1/4x + 3
