Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. t

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.
