Find the coordinates of Q so that PQ is 3/5 of PR.

Question

The point Q lies on the segment PR.

P (-13,18)

R (2,-7)

Q (?,?)

Answer 1

Take 3/5 of the difference in x coordinates and y coordinates

3/5 times 15 = 9 for the x coordinate difference. add 9 to -13 to get -4 for Q(-4, )

take 3/5 of 25 for the y coordinate difference = 15. subtract 15 from 18 to get 3 for Q(-4,3)
