Find the midpoint of R(2,2) and S(-3,6)

musickatia [10]

Answer: (-0.5, 4)

Step-by-step explanation:

Midpoint formula: $(\frac{x1+x2}{2} ,\frac{y1+y2}{2} )$

(x1, x2)=(2, -3)

(y1, y2)=(2, 6)

-----------------------------------------------

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

= $(\frac{2-3}{2} ,\frac{2+6}{2} )$

= $(\frac{-1}{2} ,\frac{8}{2} )$

= $(-0.5, 4)$

Hope this helps!! :)
