Question

what is the collinearity formula foe coordinate geometry?

Answer 1

To Find Midpoint between two points:

x=(x1+x2)2

y=(y1+y2)2

To find equation of line:

y-y1=m(x-x1)

Answer 2

Answer:

One is slope formula method and the other is area of triangle method. Slope formula method to find that points are collinear. ... With three points A, B and C, three pairs of points can be formed, they are: AB, BC and AC. If Slope of AB = slope of BC = slope of AC, then A, B and C are collinear points.
