a. The relationship can be expressed as n=5.25t
He ran 40.25 miles in 7 days, he ran (40.25)/7=5.75 miles per day.
n is the number of days, and t, the total distance he runs. Then:
[tex]t=5.75n[/tex]The statement a is false.
b. The graph of the equation is a straight line through (0,0)
This is correct because we have a linear equation in which the y-intercept is at (0,0)
The statement b is true.
c. The unit rate is 5.75.
The statement c is true as we saw with the division at the beggining.
