Observe the graph:

Consider the scale on the graph $\"\"$ -axis is $\"\"$ and $\"\"$ -axis is $\"\"$ .

The line passes through the points are $\"\"$ and $\"\"$ .

Find the rate of change.

$\"\"$ .

$\"\"$ (Formula for rate of change)

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

$\"\"$ (Subtract: $\"\"$ and $\"\"$ )

$\"\"$ (Simplify)

Therefore, the rate of change of the graph is $\"\"$ .
