To determine the unit rate of a proportional relationship from a graph displaying the cost per ounce of canned peas, you would typically look for the following:
-
Identify Points on the Graph: First, find two key points that represent different data values on the graph. These points will typically show the cost associated with a certain number of ounces of peas.
-
Calculate the Unit Rate: The unit rate is essentially the cost per one ounce. To calculate it, you can use the formula:
\[ \text{Unit Rate} = \frac{\text{Cost}}{\text{Number of Ounces}} \]
For example, if one of the points is (8 ounces, $1.20) and another point is (16 ounces, $2.40), you can calculate the unit rate for both:
-
For the first point (8 ounces, $1.20):
\[ \text{Unit Rate} = \frac{1.20}{8} = 0.15 \text{ per ounce} \]
-
For the second point (16 ounces, $2.40):
\[ \text{Unit Rate} = \frac{2.40}{16} = 0.15 \text{ per ounce} \]
-
-
Confirm Consistency: If the calculated unit rates from different points are the same, this confirms that there is a proportional relationship, and the unit rate for the cost per ounce remains constant.
Once you have identified the unit rate from the graph, you can summarize it as follows:
- The unit rate of canned peas is $X per ounce, where X is the resulting number from your calculations based on the specific points in the graph.
Without the actual graph or data points, I can't provide a specific numeric value, but you can follow the outlined steps to determine the unit rate from the graph you are analyzing.
