To calculate the rate of change of a linear function between two points, you can use the formula:
\[ \text{Rate of change} = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1} \]
From the table, we have the following points:
- For \(x = 5\), \(y = 9\)
- For \(x = 6\), \(y = 11\)
Now, we can substitute these values into the formula:
\[ \Delta y = y_2 - y_1 = 11 - 9 = 2 \] \[ \Delta x = x_2 - x_1 = 6 - 5 = 1 \]
Now compute the rate of change:
\[ \text{Rate of change} = \frac{2}{1} = 2 \]
Thus, the rate of change of the function between 5 and 6 is 2.
