7. mis the midpoint of qr and m has
coordinates (-2, 6). q has coordinates
(8, -10). what are the coordinates of r?
nges to the original content are the responsibility of the instructor.
i need on number 7

R(- 12, 22 )

Step-by-step explanation:

Using the midpoint formula

(8 + ) = = - 2

Multiply both sides by 2

8 + = - 4 ( subtract 8 from both sides )

= - 12

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

(- 10 + ) = = 6

Multiply both sides by 2

- 10 + = 12 ( add 10 to both sides )

= 22

The coordinates of R = (- 12, 22 )

it has changed from the width and the height.
