To find the linear equation that models the total cost in relation to the number of campers, we need two points on the line. The points represent the cost at a certain number of campers.
Let's analyze the options provided:
-
(0, 25) and (2, 40): This suggests that with 0 campers, the total cost is $25 (which could be the parking fee), and with 2 campers, the total cost is $40.
-
(5, 60) and (8, 80): This suggests that with 5 campers, the total cost is $60, and with 8 campers, it is $80.
-
(3, 45) and (5, 60): This shows 3 campers costing $45 and 5 campers costing $60.
-
(0, 25) and (5, 60): This has 0 campers costing $25 and 5 campers costing $60.
All of these points can be used to find a linear equation, but typically, using points that are clearly spaced helps establish the slope and y-intercept better.
To definitively find the equation, you would generally use two points that are distinct and lie on the line of the graph. Points that show a clear relationship between the cost and the number of campers would be ideal.
Therefore, (0, 25) and (2, 40) would be a great pair to use since you have a point for zero campers indicating the base fee (likely the parking fee) and a point showing a cost that includes that fee plus additional campers.
But points like (5, 60) and (8, 80) could also represent consistent linear growth, as they show an increase in cost with more campers as well.
In summary, you can use any of these pairs for modeling, but the most illustrative might be (0, 25) and (2, 40) since it effectively shows the base cost and the addition of cost in relation to an increase in campers. The answer that fits the need to find a linear equation is (0, 25) and (2, 40).
However, if the graph and visual aid indicates a specific preference for points that lie on the same straight line, the answer may change based on that observation. Without an image reference, this is a mathematical interpretation based on potential data points.
