a bathtub in your home has a drain that leaks. When you fill you bathtub with 30 gallons of water you notice that after every 5 minutes you only have 20 gallons remaining, so the drain is leaking 2 gallons every minute which represents slope. what is the linear equation of the problem and what is the y-intercept and what does it mean in the context of the problem and what is the x-intercept in the context of the problem

1. tub = -2 t + 30

the y-intercept is 30 ... a full tub

the x-intercept is the time for the tub to empty
