**2. In each of the following find the value of 'k', for which the points are collinear.**

**(i) (7, -2), (5, 1), (3, k) (ii) (8, 1), (k, -4), (2, -5)**

**Solution (i)**

(7, -2), (5, 1), (3, k)

Because, the given points are collinear, it means the area of triangle formed by them is equal to zero.

**Area of Triangle = **

**Solution (ii)**

(8, 1), (k, -4), (2, -5)

Because, the given points are collinear, it means the area of triangle formed by them is equal to zero.

**Area of Triangle = **
