Question

find the ratio in which the line segment joining the points (-3,10) and( 6,-8) is divided by (-1,6)

Answer 1

Step-by-step explanation:

[-3, 10] + r·([-1, 6] - [-3, 10]) = [-1, 6]

[-3, 10] + r·[9, -18] = [-1, 6]

-3 + 9·r = -1 --> r = 2/9

So you can cut the hole line segment in 9 parts with the same length.

So the Point [-1, 6] divided the line in 2 segments on the one side and 7 segments on the other side.

So the ratio is 2:7
