Answer:
(3/2, 9/2)
Step-by-step explanation:
You want the midpoint of the line segment with end points R(4, 3) and S(-1, 6).
The coordinates of the midpoint will be the average of the end point coordinates:
M = (R +S)/2
M = ((4, 3) +(-1, 6))/2 = (4 -1, 3 +6)/2 = (3, 9)/2
M = (3/2, 9/2) . . . . coordinates of the midpoint
