The shower head follows a linear function
From the complete question, we understand that:
Each minute, 5 gallons of water are used
This mean that, the possible ordered pairs are:
[tex]\mathbf{(x,y)= \{(1,5),(2,10),(3,15).....\}}[/tex]
When the shower head is used for 0 minutes we have:
[tex]\mathbf{(x,y)= \{(1-1,5-5)\}}[/tex]
[tex]\mathbf{(x,y)= \{(0,0)\}}[/tex]
The ordered pair when the shower head is used for 0 minutes is (0,0)
The location on the graph is called the y-intercept.
