The bucket has 3000 milliliters of water.
It leaks 18ml per minute.
Let "y" represent the remaining water after a certain number of minutes and "x" represent the number of minutes passed.
"3000ml" represents the y-intercept of the function (the amount of water in the bucket at x=0 minutes)
and "-18ml" represents the amount of water that has leaked after a certain amount of time, and is the slope of the function. The value is negative because the volume of the bucket is decreasing as time passes.
Then the function will be
