Answer:
[tex]y=-150x+1600[/tex]
Step-by-step explanation:
Linear Equation:
[tex]$y=mx+b$[/tex]
[tex]f(x)=mx+b[/tex]
Consider:
The pool is full when the time is zero:
[tex]1600=m(0)+1600[/tex]
It is emptied (-) in the rate 150 gallons every hour.
[tex]f(x)=-150x+b[/tex]
[tex]f(x)=-150x+1600[/tex]
[tex]y=-150x+1600[/tex]
