The question about "one-hour rides" means that the description is of two points. One hour is 60 minutes.

(x,y) as (10, 2.5) and (25, 4.25).
The question asks for the point (60, v).

Slope, 7%2F60
y-2.5=%287%2F60%29%28x-10%29
y=%287%2F60%29%28x-10%29%2B2.5
y=%287%2F60%29x-1%2F6%2B2.5
highlight%28y=%287%2F60%29x%2B2%261%2F3%29

The fixed cost for any ride no-matter length of time is $2.33;
which is the y-intercept.

If x is 1 hour, or 60 minutes,
y=9.33
