Answer:
[tex]y=-0.10x+60[/tex]
Step-by-step explanation:
Let
y -----> gallons of water remaining in the barrel
x-----> number of minutes elapsed
we know that
Water leaks out of the barrel at a rate of 1 gallon every 10 minutes
so
[tex]1/10=0.10\frac{gal}{min}[/tex]
The linear equation that represent this situation is
[tex]y=-0.10x+60[/tex]
