Question

1.Find a point 1/3 of the way from A to B, when A is at 4 and B is at -8. The point is located at __________.

2.Point C is located 2/5 of the way from A to B. The coordinates for A are (0,8) and the coordinates for B are (-10, 28). The x coordinate for C is ________ and the y coordinate for C is ______.

3.D is 2/3 of the way from A (-1,5) to B (5, -7). The x coordinate for D is _______ and the y coordinate for D is  ________.

Answer 1

a =4, b= -8

1/3 of the way from a to b = 12/3 = 4 plus 4 = 8

8 is 1/3 of the way from 4 to -8

(0,8), (-10,28) 2/5 of the way is (4, 16)

(-1,5), (5,-7) 2/3 of the way is (3, -3)
