Given XZ with X(-4,3) and Z (-6,-2) find the coordinates of Y if Y divides XZ one-fifth of the way from X to Z

Answer 1

-6-(-4) = -2
-2-3 = -5
So, adding 1/5 of those distances to X in both dimensions,
Y = (-4 + 1/5 * -2, 3 + 1/5 * -5) = (-4 2/5 , 2)

Actually, I suspect a typo, but you can be the judge of that.
