Interpret the meaning of the slope in the following situation:
Martina is driving home from college for winter break. Her school is 500 miles away and her distance from home can be modeled by the equation:
y=500-65x
Where y represents the number of miles she is from home and x represents the number of hours she's driven.
The slope is -65, which represents Martina's speed in miles per hour.
