Answer:
y = 120x
Step-by-step explanation:
y=mx + b is what we need where m is the slope and b is the y-intercept.
the train travels at about 120km/hour, thus the slope is 120.
y= 120x +b. to find the y intercept plug in any coordinate.
240 = 120(2) +b. you find that the y-intercept is 0.
final equation: y= 120x
Here you go! Hope this helps!
