Q10 of 46 Page 1

Find the relation between x and y if the points A(x, y), B(5, 7) and C( - 4, 5) are collinear.

As A, B and C are collinear


Then,


ar(△ABC) = 0


Using formula for a triangle if three points (x1, y1), (x2, y2) and (x3, y3) are given.



We have,



2x + 25 - 5y - 4y + 28 = 0


2x - 9y - 53 = 0
