By definition, we have that the distance traveled by the train is given by:
[tex] d = v * t
[/tex]
Where,
v: train speed
t: time
Substituting values we have:
[tex] d = 170t
[/tex]
We observe that the variables d and t are proportional.
The constant of proportionality is the speed of 170 miles per hour.
Answer:
The graph will show a proportional relationship between the variables, according to the equation:
[tex] d = 170t [/tex]
