Use the image to answer the question.
An illustration shows Quadrant 1 of a coordinate plane. The x-axis is labeled Ounces and ranges from 0 to 40 in 5 unit increments. The y-axis is labeled Cost in dollars and ranges from from 0.00 to 4.00 in increments of 0.50. The graph is titled Cost per Ounce. A line connects four points plotted on the graph. The coordinates of the plotted points are left parenthesis 0 comma 0 right parenthesis, left parenthesis 8 comma 0.80 right parenthesis, left parenthesis 15 comma 1.50 right parenthesis, and left parenthesis 30 comma 3.00 right parenthesis.
The graph displays the cost per ounce of canned peas. Use the graph to determine the unit rate of the proportional relationship.
(1 point)
The unit rate of the proportional relationship is the cost per ounce of canned peas. Based on the graph, we can see that the cost per ounce increases as the number of ounces increases. The coordinates (0,0) represent 0 ounces with a cost of $0.00, (8,0.80) represents 8 ounces with a cost of $0.80, (15,1.50) represents 15 ounces with a cost of $1.50, and (30,3.00) represents 30 ounces with a cost of $3.00.
To find the unit rate, we can look at the change in cost divided by the change in ounces. In this case, from (0,0) to (8,0.80), the change in cost is $0.80 and the change in ounces is 8 ounces. Therefore, the unit rate is $0.80 divided by 8 ounces, which simplifies to $0.10 per ounce.
So, the unit rate of the proportional relationship is $0.10 per ounce.
