Question

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

Answer 1

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%.
