Since the slope intercept form formula is y=Mx+b, your slope will be 3 and your starting point will be 0 because there’s no b. Mx is your slope and b is your y intercept.
Both of these are linear functions:
Distance A is d=2.5h and is proportional to time because the distance is just 2.5 times however many hours you have traveled.
Distance B is d= 2(h-1) + 4. This is not proportional to time but it is a linear function.
