Question

What are the coordinates of the point that is 3/5 of the way from A(-9, 3) to B(21,-2)?

A. (9, 1)
B. (3, 1)
C. (9,0)
D. (-7, 2)

Answer 1

Building and solving an equation, it is found that the coordinates are: (9,0).

We are given two points: A(-9,3) and B(21, -2).

We also want point C(x,y).

C is 3/5 of the way from A to B, thus:

This is used to find both the x-coordinate and the y-coordinate of C.

First, the x-coordinate, considering .

Then we get 9,0
