$\huge\tt\underline\orange{question}$

find the value of k. If the co ordinates of the points A(2, -2), B(-4, 2), C(-7, k) are collinear

$\huge\tt\underline\purple{solution}$

given- A,B,C are collinear whose coordinates are A(2, -2), B(-4, 2), C(-7, k)

to find - value of k

solution-

2(2-k)-4(k-(-2)-7(-2-2)= o

4-2k-4k-8+28=0

-6k-4=-28

-6k=-28+4

-6k=-24

k=4

$\huge\tt\underline\red{answer -is- 4 }$
