Find the missing endpoint if s is the midpoint of rt
r(-9,4) and s(2,-1) ; find t

T is at (13,-6)

Step-by-step explanation:

x-coordinate of T: from -9 to 2, there's 11 units, so you add 11 to 2 to find the x-coordinate of T, which is 13.

y-coordinate of T: from 4 to -1 there's -5 units, so you subtract 5 from -1 to find the y-coordinate of T, which is -6.
