Question

M(–3, –1) is the midpoint of RS. If S has coordinates (4, 6), what are the coordinates of R?

Answer 1

(–10, –8)
(–10, 13)
(11, 13)
(11, –8)

Answer 2

use the midpoint formula: x = (x1 + x2) / 2 and y = (y1 + y2) / 2

just plug is the values for each set of coordinates

example:x = -5
y = -1
x1 = 3
y1 = 3

-5 = (3 + x2) / 2
-10 = 3 + x2
-13 = x2

-1 = (3 + x2) / 2
-2 = 3 + x2
-5 = x2

Answer 3

Ohh
