To determine which points can be used to find the linear equation modeling the graph, we need to consider points that reflect the consistent increase in total cost associated with the number of campers.
In general, we start looking for two points on the line, where the first coordinate represents the number of campers and the second coordinate represents the total cost.
Here is the breakdown of the options:
-
(0, 25) and (5, 60): This indicates that when there are 0 campers, the cost is $25, and when there are 5 campers, the cost is $60. This suggests a starting value and a potential slope which could represent the parking fee and cost per camper.
-
(0, 25) and (2, 40): Again, this starts with 0 campers at a cost of $25, and with 2 campers, the total cost is $40.
-
(3, 45) and (5, 60): This suggests at 3 campers the cost is $45, and at 5 campers it is $60. This provides a good range for understanding cost increase with campers.
-
(5, 60) and (8, 80): This shows cost implications for 5 campers and 8 campers, showing an increase as well.
Any of these points can technically yield a linear equation; however, to best understand the model and the basic cost structure (such as the initial fee), we want a point that includes (0, y) to capture any fixed fees like parking.
The best choices are likely (0,25) and another point, ideally something with a low camper count.
Therefore, (0, 25) and (5, 60) is an optimal pair to identify the linear equation since it captures the start (fixed cost) and growth to a reasonable camper number.
In conclusion, (0, 25) and (5, 60) is a strong pair for finding the linear equation that models the cost structure.
