A battery with 20%20%20, percent of its full capacity is connected to a charger. Every minute that passes, an additional 5%5%5, percent of its capacity is charged.Graph the battery's capacity (in %%percent charged) as a function of time (in minutes).

y = 5x + 20

Start at (0, 20).
Then plot a point at (1, 25).

The line should be going through points (2, 30), (3, 35), (4, 40), (5, 45), etc.

For every time the x number goes up, the y number goes up 5 times for the 5%.
