Find the coordinates of the point three tenths of the way from A to B.

Question

the coordinates of b is (12,5)

the coordinates of a is (-3,-8)

Answer 1

I'm using trig.

(12,5) (-3,-8)

a^2+b^2=c^2

15^2+13^2=394^.5=19.849.....

*.3=5.9548.......(3/16,4)

Answer 2

First, find the distance between the x coordinates. 12 - (-3) = 15

Now we'll do the y coordinates the same way. 5 - (-8) = 13

To get three tenths, multiply each distance by 0.3

x = 0.3(15) = 4.5

y = 0.3(13) = 3.9

New coordinates: (4.5, 3.9)
