Question

find the value of k which the points A(7,-2) B(5,10) C(3,k) are collinear ​

Answer 1

Answer:

the given points are collinear for k=4.

Step-by-step explanation:

If three points A, B and C are collinear, then the area of triangle ABC = 0.

7-7k+5k+10-9=0.

-2k+8=0.

k=4.

Thus, the given points are collinear for k=4.
