Answer: (2,-3)
============================================================
Step-by-step explanation:
Point R is located at (-2,4)
Shift it to the right 4 units to move it to (2,4). Note how I added 4 to the x coordinate.
Then we subtract 7 from the y coordinate to move it 7 units down. We move from (2,4) to (2,-3) which is where point R' is located.
