If ba [a= (-2,-3) b= (1,2)] is extended all the way through a creating a bf and a becomes the midpoint of bf, then what are the coordinates

(-5,-8)

Step-by-step explanation:

If M(x,y) is the midpoint of the segment CD, where then

You are given two points A(-2,-3) and B(1,2), let point F be the point with coordinates (x,y). Yuo know, that point A is the midpoint of BF, then

Substitute known coordinates:

So, point F has coordinates (-5,-8)
