Let F, G, and H be collinear points on the Cartesian plane such that FG/GH =1 If F= (a,b) and H= (7a, c), then what is the x-coordinate of G?
If FG/GH = 1, then G is the midpoint of FH
So....we can use the midpoint formula to find the x coordinate of G....so we have.....
[ a + 7a ] / 2 = 8a / 2 = 4a
