Answer:
Step-by-step explanation:
Given that all three points are collinear.
Therefore the area of the triangle formed by them will be 0.
Therefore by applying the formula of area of triangle we will get the answer.
Area of triangle =
1/2[x1(y2-y3)+x2(y3-y1)+x3(y1-y2)]
0= 1/2[1(-2-6)+k(6-2)+(-5)(2-(-2))]
0= (-8+4k-20)
0= 4k-28
28= 4k
k = 28/4
k = 7
