Question

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.

To determine the unit rate of the proportional relationship shown on the graph, we can look at the slope of the line connecting the four plotted points. The unit rate represents the cost per ounce of peas.

First, we need to calculate the slope using the two points (0,0) and (30,3.00):

Slope = (3.00 - 0) / (30 - 0)
Slope = 3.00 / 30
Slope = 0.10

Therefore, the unit rate of the proportional relationship is $0.10 per ounce.
