Determine the slope of a line that passes through the following sets of points. Show your work.

(1, 1) and (4, 5)
(2, -1) and (4, 13)
(1, 18) and (-9, -2)

Slope is the change in y over the change in x

1. (1,1) and (4,5)

Slope = (5-1)/(4-1)

Slope = 4/3

2. (2,-1) and (4,13)

Slope = (13 - -1)/ (4-2)

Slope = 14/2

Slope = 7

3. (1,18) and (-9,-2)

Slope = (-2 -18)/(-9 -1)

Slope = -20/-10

Slope = 2
