Question

For the line segment whose in points are L ( 0, 2) and M (2, 8) find the Y value for the point located 3/5 the distance from L to M

Answer 1

It's 5.2

Explanation:

I got it right on my test.

Answer 2

5.6

Explanation:

The point of interest divides LM into segments of the ratio 3 : 2. The point has coordinates that are the weighted average of the coordinates of L and M with the weights being the reverse of the ratio numbers.

(2L + 3M)/5 = (2·2 +3·8)/5 = 28/5 = 5.6 . . . . y-coordinate only
