Question

use the concept of slope to explain whether the three points A(3,1), B(-2,2), and C(-4,4) can all be points on the same line.

thanks =)

Answer 1

The slopes of the lines connecting each pair of the points is different: -1/5, -1 and -3/7

They points cannot be on the same line. The three slopes would be the same if they were on the same line.
