Question

The midpoint of SM is (6,-6). One endpoint is S(2,-3). What are the coordinates of endpoint M?

Answer 1

The coordinates (x;y) of a Midpoint of a segment  AB are given by x=(x1+x2)/2  and y=(y1+y2)/2 where A(x1;y1) and B(x2;y2)

In this case you know M(1,2) and one endpoint R(-6,6)

So il will be:

1=(-6+x2)/2    that is -6+x2=2 and x2=8

and

2=(6+y2 )/2   that is 6+y2=4 and y2=-2

so the second endpoint will be (8,-2)
