If the above points are collinear, Create your account. 1/2 [ x1(y2 y3) + x2(y3 y1) + x3(y1 y2) ] = 0 or We can say that 6k = 10 8 1/2 [ x1(y2 y3) + x2(y3 y1) + x3(y1 y2) ] = 0 Area of ABC = 0 Ex 7.3 , 2 In each of the following find the value of k , for which the points are collinear. Find the values of k for which the points A(k + 1, 2k), B(3k, 2k + 3) and C(5k - 1, 5k) are collinear. So we can either find the value of its unknown coordinate by using the equation of the line or we can equate the slope of the line calculated by these points. 8( 4 + 5) + k( 6) + 2(1 + 4) = 0 2 Putting values Example 14 Find the value of k if the points A (2, 3), B (4, k) and C (6, –3) are collinear. Question 1 : Find the value of ‘a’ for which the given points are collinear. Learn Science with Notes and NCERT Solutions. In each of the following find the value of k , for which the points are collinear. x1 = 7 , y1 = 2 (ii) (8, 1), (k, 4), (2, 5) Terms of Service. i.e. Teachoo provides the best content available! x1 = 8 , y1 = 1 Find the value of ‘K’ if the points (K, 3), (6, -2) and (-3, 4) are collinear.
