In order to join an online learning community, there is a $20 startup fee and a $5 monthly fee. Write an equation in slope-intercept form that models this situation.

• the slope is 20 dollars because that was the start up fee

• the slope was $5.00, because each month costs $5.00

• the y intercept is $20 because each month costs $20

• the y intercept is 5.00 because each month costs 5.00
