If you have more than one question, you need to make separate posts.

The slope of a straight line is the rise divided by the run.  In this case, the "rise" is the distance y in feet, and the "run" is the time x in hours.  This means the the slope is

`m=y/x`

which is given in units of feet per hour.  

The slope in this line represents the speed of the person walking in feet per hour.
