X and Y Intercepts HWName:Period:

1) The clownfish tank at the aquarium was being emptied at a constant rate for cleaning. When Alli arrived at work, she noted that there was still 10 feet of water in the tank.

Alli started a table to record the height, as shown below. Fill in the table by completing the missing values. Then plot the data on the graph and write the linear equation.

x (hours after Alli arrived) / -5 / -1 / 0 / 1 / 2 / 3 / 5
y (height in feet) / 12 / 10 / y =

a) Does it make sense to connect the points? Why or why not?

b) What will the height of the water be two hours after Alli gets to work?

c) If the water level is 20 feet when the tank is full, how many hours before Alli got to work did Roland open the drain?

d) How many hours did it take to drain it completely?

e) What is the x-intercept? ( , ) What does that point tell you about the water in the tank?

f) What are the coordinates of the y-intercept? ( , ) What information does it give about the water in the tank?
