When Something Is Collinear?

When three or more points lie on a straight line. (Two points are always in a line.)

What does it mean for points to be collinear?

Three or more points are said to be collinear if they all lie on the same straight line. If A, B and C are collinear then m A B = m B C ( = m A C ) .

How do you determine if points are collinear?

Three or more points are collinear, if slope of any two pairs of points is same. 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.
