Slope Intercept Rate of Change

A water tank is being filled by pumps at a constant rate. The volume of water in the tank V, in gallons, is given by the equation: V(t) = 65t + 280, where t is the time, in minutes, the pump has been on. At what rate, in gallons per minute, is the water being pumped into the tank?

The table represents the gallons of water being drained from a pool given the number of hours the pump is running. Find the rate of change and explain what it means for the situation

• -2/1; 2 gallons are being pumped out every 1 minute

• 20/10; 10 gallons are being pumped out every 20 minutes

• 10/20; 10 gallons are being pumped out every 20 minutes

• -1/2; 2 gallons are being pumped out every 1 minute

Find the slope:

• 3/4

• 4/3

• -3/4

• -4/3
