Question

Point A has coordinates (-5, 3). If point (1,6) is

of the way from A to B what are the coordinates of point B?

Answer 1

`(3, 7)`

Explanation:

(4/3)P -(4/3)A + A = B . . . . . . add A

(4P -A)/3 = B . . . . . . . . . . . . . simplify

Then the coordinates of point B are ...

B = (4(1, 6) -(-5, 3))/3 = (9, 21)/3

B = (3, 7)
