Question

R(-9, 4) and S(2, -1); Find T.

Answer 1

R(-9, 4) and S(2, -1); Find T.

we know that

The formula to calculate the midpoint between two points is equal to

$M(\frac{x1+x2}{2},\frac{y1+y2}{2})$

In this problem we have

(x1,y1)=R(-9,4)

(x2,y2)=S(2,-1)

substitute the given values in the formula above

$\begin{gathered} M(\frac{-9+2}{2},\frac{4-1}{2}) \\ M(-3.5,1.5) \end{gathered}$

therefore

point T(-3.5,1.5)
