Mr. Melendez has a pool in his house. The pool is 50 inches tall, but he never fills it all the way up. One day he notice the pool had a very small leak in it. The graph below shows how fast the water leaks out of the pool. How many days until the pool is completely dry and has no more water in it?

• 7

• 8

• 9

• 10

What is the meaning of the y-intercept?

• The weight in the bucket increases by 1 pound per pound of sand.

• Before sand is put in the bucket, it weighs 1 pound.

• The starting weight of the sand is 1 pound.

• The weight in the bucket decreases by 1 pound per pound of sand.

If the line continued in both directions, what would the y-intercept be?
