Final answer:
The slope of the line is 3.
Step-by-step explanation:
The slope of this line is 3.
The slope is defined as the rise divided by the run, and in this case, there is a rise of 3 on the vertical axis for every increase of 1 on the horizontal axis.
This means that for every 1 unit increase in the x-coordinate, the y-coordinate increases by 3 units.
