Question

Find the slope of the line through each pair Of points.

1. (1,5) and (2,8)
2. (3,1) and (3,-1)

Answer 1

In order to find the slope between a set of points you must plug the points into the point slope formula ; ( y2-y1 / x2-x1 )

Once you plug that in you should get the final answers of

1. slope = 3

2. slope = -2/0 which is undefined which means this slope would be part of a vertical line
