Find the coordinates of R.Answer by drj(1380)   (Show Source): You can put this solution on YOUR website!M is the midpoint of QR. Q has coordinates (-3,5), and M has coordinates (7,-9). Find the coordinates of R. Step 1. The midpoint is calculated as the average of the x-coordinates and y-coordinates between the two points. Let (x,y) be the coordinates of R. Step 2. x-coordinate of midpoint is found as Step 3. y-coordinate of midpoint is found as Step 4. The other endpoint R is (17,-23) I hope the above steps were helpful.
