Answer:
The slope is 1/2
Explanation:
The slope is rise over run, from point 1 to point 2 the line rises 3.
The run from point 1 to point 2 is 6.
That means that rise over run is 3/6
Simplify this so that it is in the simplest form to get 1/2.
The image shows the rise and the run.
I hope this helps you out :D
