Question

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

Answer 1

Use the slope formula:
`(y2-y1)/(x2-x1)`

1. (4, 9), (1, -6)

`(-6-9)/(1-4) = (-15)/(-3) = 5`

2. (2, 5), (6, 2)

`(2-5)/(6-2) = (-3)/(4)`

3. (4, 3.5), (-4, 3.5)

`(3.5-3.5)/(-4-4) = (0)/(-8) =0`

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

`(-5-(-2))/(-2-1) =(-3)/(-3) = 1`
