Answer:
Step-by-step explanation:
The distance a baseball travels when a player hits the ball varies directly with the speed with which the player swings the bat.
The graph below shows the distances a baseball travels (in feet) and the speed of the swing (in miles per hour).
Based on the graph, which relationship exists between the speed of the swing and the distance the ball travels?
A. The distance is 0.1 times the swing speed.
B. The distance is 0.2 times the swing speed.
C. The distance is 5 times the swing speed.
D. The distance is 10 times the swing speed.

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.
We know the formula , Distance = speed * time
Speed is constant and it is 12. So it is linear
The function becomes d = 12t, x is the t is the time and d is the distance
At the starting point, t=0 and distance d=0
End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9
So domain (t) is {}
Range (d) is {}
