The equation is $\"\"$ .

Find the rate of change.

The linear equation is $\"\"$ .

$\"\"$ .

$\"\"$ (Original equation)

$\"\"$ (Subtract $\"\"$ from each side)

$\"\"$ (Apply additive inverse property: $\"\"$ )

$\"\"$ (Divide each side by $\"\"$ )

$\"\"$ (Cancel common terms)

$\"\"$ (Rewrite the equation)

$\"\"$ (Simplify)

Compare the both equations are $\"\"$ .

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