The answer is (5,-2)
If we look at points P and P’, the transformation preserves all points along the x direction and moves the point twice its y coordinate down along the y direction. So point P has gone from (7, 6) to (7, 6-12) = (7, -6). Thus, the point R(5, 2) would be moved to (5, 2-4) = (5, -2).
The correct choice is 4. The coordinates of R’ are (5,-2). Step by step explanation: We consider that after reflection the triangle P’Q’R’ is an image of the triangle PQR. If the figure is mirrored on the x-axis, the x-coordinate stays the same, but the sign of the y-coordinate changes. If the figure is mirrored on the y axis, the y coordinate remains the same, but the sign of the x coordinate changes. It is given that P(7,6) and P'(7,-6). As the x coordinate remains the same, the PQR figure is therefore reflected on the x axis. The point is Q(3.5). The point is R(5,2). Therefore, the coordinates of R’ are (5,-2). Option 4 is correct.
(5,-2) is the answer
