Answer 2

$\mathcal \green {{SOLUTION:-}}$

Let A, B and C be the points.

•°• A = (1,2), = (x1, y1)

B = (-5,6), = (x2,y2)

C = (a,-2) = (x3, y3)

Points are collinear ...... given

•°• slope of AB = slope of BC

•°• (y2 - y1)/(x2 - x1) = (y3 - y2)/(x3 - x2)

(6 - 2)/(-5 - 1) = (-2 - 6)/(a - (-5))

4/-6 = - 8/(a + 5)

1/-6 = -2/(a + 5)

-6 × -2 = 1(a + 5)

12 = a + 5

12 - 5 = a

7 = a

The value for a is 7.
