You are draining a fish pond. the amount y in liters of water remaining after x hours is y equals -60x + 480 a graph the equation be interpreted the x and y intercepts

The graph in the attached figure

see the explanation

Step-by-step explanation:

Let

x----> the time in hours

y ----> liters of water remaining in the fish pond

we have

This is the equation of a line in slope intercept form

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope or unit rate is equal to

----> is negative because is a decreasing function

The y-intercept or initial value is

The graph in the attached figure

Remember that

The y-intercept is the value of y when the value of x is equal to zero

The y-intercept is the point (0,480)

That means----> The initial amount of liters of water in the fish pond was 480 liters before drainage began (for x=0 hours).

The x-intercept is the value of x when the value of y is equal to zero

The x-intercept is the point (8,0)

That means----> The time required to empty the fish pond is 8 hours (for y=0 liters)

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
