What is the equation of the line with a slope of -2 that passes through the point (4, -3)? y + 3 = 4(x - (-2)) y + 4 = -2(x - 3) y + 3 = -2(x - 4) y + 4 = 3(x - (-2))

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
