A max subscription for Twitch, a streaming service, costs a flat fee of $25. You can then also buy small subscriptions for other
s for $5 per subscription. Johnny is trying to budget the amount of money he wants to spend. Let y represent the total amount of money spent, and x represent the number of small subscriptions he purchases.
Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.
