Question 926273: An automated production line uses distilled water at a rate of 300 gallons every 2 hours to make shampoo. After the line had run for 9 hours, planners noted that 2,100 gallons of distilled water remained in the storage tank. Write a linear equation relating the time t in hours since the production line began and the number of gallons g of distilled water in the storage tank. Write the equation in slope-intercept form.

rate of water use = 300/2 = 150 gl/hr
---
water use after 9 hours = 150 * 9 = 1350 gl
---
volume in tank at start of production = 1350 + 2100 = 3450 gl
---
answer:
g = -150t + 3450
