Answer: For each hour that Michelle drove, she travelled an additional 50 miles.

Explanation:

Test each option to see its accuracy

Calculate the slope:

$(x_(1), y_(1)) = (7, 0)\\(x_(2), y_(2)) = (0, 350)\\ \\(y_(2)-y_(1))/(x_(2)-x_(1)) =(350-0)/(0-7) =(350)/(-7) =-50$

This means that Michelle drove 50 miles per hour.

The other three options are wrong because if you bring in:

into your function- y = -50x + 350, you would not get the stated miles.
