(a) To find an equation to represent the relationship between C and T, we need to determine the pattern in the data. Looking at the graph, we can see that as the time T increases by 1 second, the amount of candy C increases by 100 grams. This tells us that the rate of change is 100 grams per second. We can use this information to write the equation:
C = 100T
(b) The correct statement to represent this relationship is:
The machine is filling the container with 100 grams of candy per second.
A machine is filling a container with candy. The graph below shows the relationship between the amount of candy C (in grams) in the container and the time T (in seconds) since the machine began filling the container.
