A bottle of water costs $1.50. Explain how you would make a graph of four ordered pairs to model the total cost of the water in terms of the number of bottles.
pick 4 numbers (bottles)
multiply each by the unit cost, 1.50
Now plot the pairs: (bottles, cost)

To create a graph of four ordered pairs to model the total cost of the water in terms of the number of bottles, you need to understand the relationship between the number of bottles and the total cost. In this case, it is mentioned that each bottle costs $1.50.
1. Start by deciding on a range of values for the number of bottles. Let's say we choose to consider 0, 1, 2, and 3 bottles.
2. Next, determine the total cost for each number of bottles. Here is the calculation for each ordered pair:
- For 0 bottles, the total cost would be 0 since there are no bottles: (0, 0)
- For 1 bottle, the total cost would be $1.50: (1, 1.50)
- For 2 bottles, the total cost would be $3.00: (2, 3.00)
- For 3 bottles, the total cost would be $4.50: (3, 4.50)
3. Once you have the four ordered pairs, you can plot them on a graph. The x-axis represents the number of bottles, and the y-axis represents the total cost. Start by labeling the x-axis from 0 to 3 (or any other range you chose).
4. Plot the four points on the graph based on the ordered pairs you calculated:
- (0, 0) would be plotted at the origin (0,0)
- (1, 1.50) would be plotted at (1, 1.50)
- (2, 3.00) would be plotted at (2, 3.00)
- (3, 4.50) would be plotted at (3, 4.50)
5. Connect the points with a line. Since there are only four points, this line would be a straight line connecting the plotted points.
This graph represents the relationship between the number of bottles and the total cost of water. As the number of bottles increases, the total cost increases linearly at a rate of $1.50 per bottle.
