Question

If the points A (2, 3), B (5, k) and C (6, 7) are collinear, the value of k is:

(a)11/4
(b)4
(c)– 3/2
(d)6​

Answer 1

Answer:

The answer is B-(4)

Step-by-step explanation:

If point are collinear the distances between point is equal

hence,

d(AB)=d(BC)

by applying distance formula

and solving

you will arrive somewhat like this

8k+18-50=0

8k-32=0

8k=32

So, k=4
