You water the plants in your classroom at a constant rate. After 5 seconds, your watering can contains 58 ounces of water. Fifteen seconds later, the can contains 28 ounces of water.

a. Write an equation that represents the amount y (in ounces) of water in the can after x seconds.

b. How much water was in the can when you started watering the plants

c. When is the watering can empty

## Answers ( No )

So, the original amount was 58 ounces , then in 15 secs, we get 28, So the amount we lost was 30 by 15, giving us the slope of

2 ounces lost per second.Now that we know the slope, we can answer the questionsA. We can get the equation by finding the y int. (below) and writing it as

y=-2x+68B. Since we lost 2 ounces per second, we need to add up 2 ounces for every second lost. 2×5=10+58=

68 ounces at the beginning.C.Since we have the formula and the slope, we just need to find when y hits 0. and that is:

After 34 seconds.
