Respuesta :

Given data:

The given fixed distance is d=1 mile.

The given rate is m=3 miles/hr.

The expression for the total distance is,

D=d+mt

Substitute the given values in the above expression.

D=1+(3)t

The value of distance at t=0 is 1 mile, so the graph must pass through (1,0) and the slope is 3 miles/hour.

Thus, the correct option is C.
