Rachel's backyard pool is being emptied by a pump. The amount of water (W) in the pool in gallons, at any time (t) in hours is given by the following equation:
W= 1800-300
How many gallons of water are being pumped out each hour? Just fill in the number.

If you are saying that 300 gallons of water are being pumped out each hour then it will take 6 hours to pump out all of the water.

Step-by-step explanation:

To find that answer all I did was divide 1800 by 300. I don't know if that is the answer your looking for but I tryed sorry.

step-by-step explanation:

let

we know that

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

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
