Question

verify that the points A(4,2),B(7,5)c(9,7) are collinear or not​

Answer 1

THE THREE POINTS ARE COLLINEAR

Answer 2

To prove the points are collinear, take out the area of the triangle formed using the area formula, and if it comes out to be 0, then the points are collinear.

Formula=1/2|x1(y2-y3)+X2(y3-y1)+X3(y1-y2)|
