Answer:
yes
Step-by-step explanation:
proportional and liner functions almost identical informed the only difference is that the be of the constant of the liner function. Indeed a proportional relationship is just a line of relationship where be equal 0 or to put it another way when the line passes through the origin 0,0

Step-by-step explanation:
The image of the motion of Paul's derive is attached already.
From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.
What is average speed?
Average speed is the rate of change of total distance covered with time taken .
Average speed = 
To find the total distance covered;
Distance at time 1 = 75miles
Distance at time 4 = 225miles
Distance covered between 1 - 4 = 225 - 75 = 150miles
Time taken for the journey = 4 - 1 = 3hrs
Input the values in the equation;
Average speed =
= 50mph

T=21+4.5X
21 is the original temp.
4.5 is the constant rate I got when I subtracted 75-21=54 then divided 54/12min=4.5.
75 =21 + 4.5(12)
Proportionality, assuming constant rate. 460 dives/12 hours = x dives/3 hours. Solve for x.
