Mathematics

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

Step-by-step explanation:

Test each option to see its accuracy

Calculate the slope:

$(x_{1}, y_{1}) = (7, 0)\\(x_{2}, y_{2}) = (0, 350)\\ \\\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{350-0}{0-7} =\frac{350}{-7} =-50$

This means that Michelle drove 50 miles per hour.

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

x = 6x = 3

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