Answer:
yes, its a linear function
Step-by-step explanation:
g= -2 1/2m+20
Yes it represents a linear function because the equation takes the idea of y=mx+b.
g= represents gallons of water left
-2 1/2m= is the rate of the water draining, which is the slope, in the linear function.
x= represents the number of minutes
b= represents the start amount of gallons of water.
hope that helps!
