An hourglass is turned over with the top part filled with sand. After 3 minutes, there are 855 mL of sand in the top half.
After 10 minutes, there are 750 mL of sand in the top half. What is the y-intercept?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

The rate is %28855-750%29%2F%2810-3%29 = 105%2F7 = 15 mL of sand per minute.


Now add 3*15 mL to 855 mL. You will get 900 mL.


It is your answer.


Now you think why.
