A line segment with endpoints at P(1,8) and Q(5,−2) is reflected across the y-axis and translated up 6 units. What are the coordinates of the image of point Q?

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.
