Question

Find the slope of the line on the graph. Reduce all fractional answers to lowest terms.

Answer 1

Graph 1: -1
Graph 2: 2
Graph 3: -1/3

Answer 2

Slope:
`(y2 - y1)/(x2 - x1)`

1) (-2, 2), (2, -2)
Plug these points in.

`(-2 - 2)/(2 - (-2))`

`(-4)/(4)` = -1
The slope is -1.

2) (1, 2), (-1, -2)
Plug these points in.

`(-2 - 2)/(-1 - 1)`

`(-4)/(-2)` = 2
The slope is 2.

3) (-2, 2), (4, 0)
Plug these points in.

`(0 - 2)/(4 - (-2))`

`(-2)/(6)` = -
`(1)/(3)`
The slope is -1/3.
