To reflect the rectangle over the x-axis, think of it as flipping it over the x-axis. On the graph, count the units from V to S, it's 6 units. So, from the x-axis, count 6 units up from V. S would lie on -6, 6. Do the same for W to T. T would lie on (2, 6). The remaining coordinates U and V don't change because it is <em>already </em>on the x-axis. <em> </em>
So z-4 2/3=2 2/3 so 4 2/3=12/3+2/3=14/3 2 2/3=6/3+2/3=8/3 z-14/3=8/3 multiply both sides by 3 3z-14=8 add 14 to both sides 3z=22 divide both sides by 3 z=22/3=7 1/3
