Question

If the point P(k, 0) divides the line segment joining the points A(2, -2) and B(-7, 4) in the ratio 1:2, then the value ofk is

Answer 1

Answer:

-1

Step-by-step explanation:

the point P(k, 0)

points A(2, -2) and B(-7, 4)

ratio = x1-x:x-x2

1:2 = 2-k : k- (-7)

1:2 = = 2-k : k+7

k+7=2(2-k)

k+7=4-2k

3k= -3

k=-1
