To find the unit rate of the proportional relationship shown in the graph, we need to calculate the cost per ounce at different points plotted on the graph.
The plotted points give us the following values:
- At (0, 0): 0 ounces cost $0.00.
- At (8, 0.80): 8 ounces cost $0.80.
- Unit Rate = Cost / Ounces = 0.80 / 8 = $0.10 per ounce.
- At (15, 1.50): 15 ounces cost $1.50.
- Unit Rate = 1.50 / 15 = $0.10 per ounce.
- At (30, 3.00): 30 ounces cost $3.00.
- Unit Rate = 3.00 / 30 = $0.10 per ounce.
From all the points calculated, the unit rate of the proportional relationship is consistently $0.10 per ounce.
