Mark the tick against the correct answer in the following:

If the points A(3, -2), B(k, 2) and C(8, 8) are collinear then the value of k is


To find: Area of ABC


Given: A(3,-2), B(k,2) and C(8,8)


The formula used:


We have, A(3,-2), B(k,2) and C(8,8)



Expanding along R1




-18 +2k - 16 + 8k -16 = 0


10k -50 = 0


k = 5
