Slope is found by doing this formula:
[tex] \frac{rise}{run} [/tex]
So, if we graph the points. We will see that the y value changes
[tex]11-8=3[/tex]
That's our rise.
Then, for the run
[tex]12-3=9[/tex]
The slope would look like this
Our fraction: [tex] \frac{3}{9} [/tex]
[tex]3/9=0.3333...[/tex]
That's our slope!
