A(2, 5), B(−1, 2) and C(5, 8) are three points. Show that they are collinear by finding the slopes of AB and BC.
Original Khojo Papers practice question — not from a past board paper.
Answer
Both slopes are 1, so the three points are collinear.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Slope of AB = (2 − 5)/(−1 − 2) = 1 and slope of BC = (8 − 2)/(5 + 1) = 1. Two segments with a common point and equal slopes lie on the same line.
