What is the x axis? What is the y axis

Question

The machine can stuff a batch of envelopes in 5 hours.  How long would it take the machines to stuff 10 batches of envelopes?  14 batches of envelopes?

 

I know one equation is 5*10 & other is 14*10 but how you get which axis and where intercept and slope?

Answer 1

We determine how many batches of envelopes

are stuffed based on how many hours the macine

runs.  Thus, the number of batches of envelopes

is a function of the number of hours.  This means

the  "x-axis" is hours and the "y-axis" is number

of batches of envelopes stuffed.

 

If b = # batches stuffed, and

h = number of hours run, your

equation is:

 

b = 5h

or

y = 5x

with y representing batches stuffed

and x representing number of hours

 

The slope is 5

 

The "x-intercept" where y = 0 is (0,0)

 

The "y-intercept" where x = 0 is also (0,0)

 

This makes sense considering if the machine

runs zero hours then zero batches get stuffed.
