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)

B is the correct answer. To find out how long AC is, you must first find the length of AB. To do that, form a triangle by finding the point where perpendicular lines from points A and B meet. According to Pythagoras’ theorem, a^2 + b^2 = c^2. Thus 16^2 + 8^2 = c^2. 256 + 64 = c^2. The square root of this is 17.9. AB is therefore 17.9 units long. 3/4 of 17.9 is 13.4 AC is 13.4 units long. The co ordinate that fits this is (2,0).
