You are using a hose to fill up your backyard swimming pool on a hot day. Water flows out of the hose at a rate of 6 gallons per
minute. In the equation below, m is the number of minutes the hose has been running, and g is the number of gallons of water in the pool. The relationship between these two variables can be expressed by the following equation:
g=6m,
Identify the dependent and independent variables.
The independent variable is the m, which is the number of minutes the hose has been running. The dependent variable is the g, which is the gallons per minute.
