Answer:
Look at the graph of the relationship. Find two points which have y-values that are one unit apart. The unit rate is the difference in the corresponding x-values.
Explanation:
To find the unit rate for a proportional relationship, you need to identify any two points on the graph of the relationship that have y-values that differ by one unit. Once you have identified these two points, you can find the unit rate by calculating the difference between the corresponding x-values (the change in x) for those two points:
1. Look at the graph of the proportional relationship.
2. Identify any two points on the graph that have y-values that differ by one unit.
3. Determine the x-value for each of the two points you identified in step 2.
4. Calculate the difference between the two x-values (the change in x) for those two points.
5. The result of step 4 is the unit rate for the proportional relationship.
