Question

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

Answer 1

Midpoint formula: \[\frac{ x_1 + x_2 }{ 2 }, \frac{ y_1 + y_2 }{ 2 }\]
Plug in what you know
\[\frac{ 4 + x_2 }{ 2 } = -3\]
\[\frac{ 6 + y_2 }{ 2 } = -1\]
solve for x2 and y2

Answer 2

Okay thanks
