Using linear function concepts, it is found that the correct option is:

A. If the automobile was going 30 mph, the slope of the line is 30.

A linear function is modeled by an equation in the following format:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change.
b is the y-intercept, which is the value of y when x = 0.

In this problem, the relationship between time and distance traveled is proportional, which means that slope is given by the velocity. Thus, the correct option is:

A. If the automobile was going 30 mph, the slope of the line is 30.
