This storyboard does not have a description.
Well after 40 seconds there is 13 gallons left and after 1 minute there is 10 gallons left so it looks like we will have to do some math
How long will it take for the bathtub to drain?
Well come on i will show you
Well how do you do that
We need to find our slope so, the basic slope intercept form is y = mx + b. We will use this an the information we already have to find out how long it will take until the bathtub is completely empty
We know that it took 40 seconds for 13 out of 19 gallons to drain now we have to find the m value of our equation
