Answer:
Slope can be found by determining the ratio of the rise (vertical change) to the run (horizontal change).
In this case miles is the rise, and 3 hours is the run
It should rise 12 and go over 3
I cannot really make out what's on your screen but it's likely it would be D.
The line has to pass 3, it cannot be off 3 by a bit.
And it should be lower than 20 because it rises 12.
