Distance & Midpoint Formulas Find the missing endpoint if S is the midpoint RT
1. R(-9,4) and S(2, -1); Find T.
2. S(-4, -6) and T(-7, -3); Find R

Step-by-step explanation:

1. The question doesn’t state what T represents, so I will assume T is one of two points:

1. The midpoint of R and S, or

2. S is the midpoint of RT.

1. T((-9+2)/2,(4-1)/2)=T(-7/2,3/2)

2. T(x,y): S(2,-1)=((-9+x)/2,(4+y)/2); 2=(-9+x)/2, 4=-9+x, x=13; (4+y)/2=-1, 4+y=-2, y=-6. T(13,-6)
