Answer:

The coordinates of R x= -10 , y=6

Step-by-step explanation:

The midpoint between two points (x1 , y1) and (x2 , y2) is

[tex](\frac{x1+x2}{2} ,\frac{y1+y2}{2} )[/tex]

[tex]0=\frac{10+x2}{2}[/tex]

10 +x2 = 0

x2 = -10

[tex]8=\frac{10+y2}{2}[/tex]

10 + y2 =16

y2 = 16 -10 = 6

Point R is (-10 , 6)
