Juno is taking a taxi. the table represents a linear function and shows the amount she owed after various numbers of miles traveled. is the rate of change 2.25?

Check the attached image showing the table associated with the question

Yes, because the amount owed changes by 2.25 every time the miles change by 1

Explanation:
The rate of change can be referred to as the slope of the function.
The slope can be calculated using the following formula:
slope = 

We will get the slope between each two successive points:
between 1 and 2:
slope = 

between 2 and 3:
slope = 

between 3 and 4:
slope = 

between 4 and 5:
slope = 

We can note that as the miles increase by 1, the amount charged increase by 2.25.
This means that the rate of change is 2.25

Hope this helps :)
