Triangle ABC is reflected over the x-axis. What are the coordinates of the image of the vertex A?

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

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.
