Question

Try yourself
1. Prove that P(13, 14), Q(5,8) and R(1.5) are points
on a line.​

Answer 1

Step-by-step explanation:

If the points lie on same line they must have their slope equal!

slope of PQ = -6/-8 = 6/8 = 3/4

slope of QR = -3/-4 = 3/4

slope of PR = -9/-12 = 3/4

Since their slopes are same they lie on a line
