Identify coordinates from the table
We select two points from the table to calculate the rate of change. Let's choose:
\[(x_1, y_1) = (1, 5)\]
\[(x_2, y_2) = (2, 5)\]
Apply the rate of change formula
The rate of change is the ratio of the change in \(y\) to the change in \(x\):
\[\text{Rate of Change} = \frac{y_2 - y_1}{x_2 - x_1}\]
Calculate the values
Substitute the coordinates into the formula:
\[\text{Rate of Change} = \frac{5 - 5}{2 - 1} = \frac{0}{1} = 0\]
