This is a linear function because the graph of the relationship between the number of gallons of water in the pool (g) and time in hours (t) forms a straight line. The rate at which water is added to the pool remains constant, meaning that for every hour that passes, the amount of water increases by a fixed amount (500 gallons), resulting in a linear increase in the total gallons of water over time.
A community swimming pool starts with 250 gallons of water. Julian starts filling the pool at a rate of 500 gallons per hour.
The relationship between the number of gallons of water in the pool and the time in hours is a linear function. Complete the sentence to explain why.
