(i) (2, 3), (-1, 0), (2, -4)
(ii) (-5, -1), (3, -5), (5, 2)
Solution:
Ex 7.3 Class 10 Maths Question 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) Since the given points are collinear, the area of the triangle formed by them must be 0, i.e.,
(ii) Since the given points are collinear, the area of the triangle formed by them must be 0, i.e.,
Ex 7.3 Class 10 Maths Question 3.
