Question

per minute. the graph below represents the relationship between the number of minutes and gallons of water in the pool. you just found that the slope is 12. what does a slope of 12 mean in this situation? the pool is being filled with water at a rate of 12 gallons for every 1 minute. the pool is being filled at a rate of 1 gallon of water for every 12 minutes. the pool starts with 12 gallons of water in it.

Explanation:

Slope represents the rate of change of the dependent variable (gallons of water, $y$) relative to the independent variable (minutes, $x$). A slope of 12 means for each 1-unit increase in $x$ (1 minute), $y$ (gallons) increases by 12. The y-intercept (starting gallons) is 2, not 12, so the third option is incorrect. The second option reverses the rate.

Answer:

The pool is being filled with water at a rate of 12 gallons for every 1 minute.
