Full solution stays hidden until you ask for it.
1. Use the rate as the coefficient of x.
2. Use the initial value as the constant term.
3. Write the model in slope-intercept form.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
