Sam is filling up his pool. The water hose filled the 423 gallon pool in 47 minutes. At what rate did the hose fill the pool in gallons per minute?

9 gallons/minute

Step-by-step explanation:

Since you are trying to find gallons/min, there are two ways you can go about this. Either find a common factor between the 2 number, or you can simply to divide 423 by 47. Thankfully in this situation, you can find the answer easily either way because 47 is a factor of 423.

Factor out 47:

423 gallons/47 minutes

47*9 gallons/47*1 minutes

Simplify:

9 gallons/minute

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
