What is the equation of the line that passes through the point (-4, 8) and has a slope of zero? X = -4 y = -4 C x = 8 D y = 8

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
