Answer :
The slope of the line is the rate of change of y with respect to x. Since the units are already gallons and minutes, the rate that the water is being pumped is 65 gallons per minute. Hope this helps! :)
so V(t)=65t+280
this is like y=mx+b
m is the slope/rate so the rate is 65gallons per minute
just for fun, the tank had 280 gallons origonally
