Answer:
the slope is -1/2 while the y-intercept is 80
Step-by-step explanation:
Let x be the time in minute and y be the water in the gallon.
From the question, the water flows at a rate of 1 gallon every 2 minutes, which implies that, the rate of change is the slope = 1/2.
The tank has a leak i.e The water flows out from the tank. Since the water flows out of the scope,it implies that the scope = -1/2. y- intercept is the initial amount of water in the tank which is 80.
