Question

find the value of k if the coorinates of the points A(2,-2),B(-4,2)&C(-7,k) are colinear​

Answer 1

Answer:

4

Step-by-step explanation:

condition for collinearity:slope of AB=Slope of BC

A(2,-2) B=(-4,2) C=(-7,k)

slope m=(y2-y1)/(x2-x1)

2+2 k-2

____ = _____

-4-2 -7+4

4/-6=(k-2)/-3

2=k-2

k=4
