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 =)

math 
drwls,
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.
