Question

Please please help me!!!!

Answer 1

Answer:

Q = (9, 4 )

Step-by-step explanation:

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

M = ($\frac{x_{1}+x_{2} }{2}$ ) , ($\frac{y_{1}+y_{2} }{2}$ )

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

$\frac{x-7}{2}$ = 1 ( multiply both sides by 2 )

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

x = 9

and

$\frac{y+0}{2}$ = 2 ( multiply both sides by 2 )

y = 4

Thus Q = (9, 4 )
