Answer:

Q = (9, 4 )

Explanation:

Use the midpoint formula and equate to the coordinates of the midpoint.

M = (
(x_(1)+x_(2) )/(2) ) , (
(y_(1)+y_(2) )/(2) )

let the coordinates of Q = (x, y ) , R = (- 7, 0 ) , then


(x-7)/(2) = 1 ( multiply both sides by 2 )

x - 7 = 2 ( add 7 to both sides )

x = 9

and


(y+0)/(2) = 2 ( multiply both sides by 2 )

y = 4

Thus Q = (9, 4 )
