Question

Given A (-6,4) and M(-1, -1) find B.

Answer 1

what is B?

Answer 2

thats all the information they gave me

Answer 3

oh M is midpoint? if so then you know that if B has coordinates (x,y) you get
\[\frac{-6+x}{2}=-1\]
\[\frac{4+y}{2}=-1\]

Answer 4

first equation give \[-x+6=-2\]
\[x=8\]

Answer 5

second equation gives
\[4+y=-2\]
\[y=-6\]

Answer 6

so B is (8,-6)

Answer 7

hold on i must have made a mistake somewhere

Answer 8

oh yes

Answer 9

(-6, -4)

Answer 10

first equation is
\[-6+x=-2\]
\[x=4\]

Answer 11

B is (4,-6)
