Question

Points A (-10,-6) and B (6,2) are the endpoints of AB. What are the coordinates of point C on AB such that AC is 3/4 the length of AB?
a. (0,-1)
b. (2,0)
c. (-2,-2)
d. (4,1)

Answer 1

$(\frac{x_{1} + x_{2}}{2}, \frac{y-{1} + y_{2}}{2}) \\(\frac{-10 + 6}{2}, \frac{-6 + 2}{2}) \\(\frac{-4}{2}, \frac{-4}{2}) \\(-2, -2)$

The answer is C.
