A bucket holding 20 gallons of water is leaking at a rate of 1.5 gallons per minute. Write a function that could be used to determine the the amount of water in the bucket after x minutes. Not all answers will be used

y = ​ ​ ​ (a)   x + ​ (b)  

• -1.5
• 20
• 0.5
• -20
• 20.5
• -20.5

Answer explanation

How much water did the bucket start with? This is the y-intercept. How much is leaking EACH minute? This is the rate of change. And since it is leaking, is that adding to the amount of water in the bucket or subtracting from it?
