To show:
The given table represents a linear function. Then write an equation for the function.
Answer to Problem 25E
The table represents a linear function. Our required equation would be
Explanation of Solution
Given:
A table:
Calculation:
To show whether our given table represents a linear function or not, we will see if the values in table has a constant rate of change.
We can see from our table that as x increases by 2 units, y increases by 1 unit.
So our given table has a constant rate of change that is equal to
The slope of line is
Therefore, our required equation would be
