What is the equation of the line in point slope form that goes through (-2,-1) and is perpendicular to y=5x+3?

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.
