Find the slope of the line that passes through each pair of points.

Question

1. (2,5), (3,1)
2. (-1,2), (-5,2)
3. (5,2), (2,-3)
4. (4,3), (-2,-6)

Answer 1

1. 4/-1 = -4
2. slope = 0. 2-2 = 0, it's a flat horizontal line, regardless of the x values, unless the x values were equal
3. 5/3
4. (3+6)/(4+2) = 9/6 = 3/2

just subtract the y values and divide them by the difference in the corresponding x values
