Answer:
f(x) = - 3x + 4
Step-by-step explanation:
Note that y = f(x)
Given
9x + 3y = 12 ← Rearrange making y the subject
Subtract 9x from both sides
3y = - 9x + 12 ( divide all term by 3 )
y = - 3x + 4, thus
f(x) = - 3x + 4
The earning of the salesperson is an illustration of a linear function.
The possible functions in the two scenarios are:
and 
The function is given as:

When the base salary is increased, a possible function is:

This is so, because 2500 is greater than 2000
When the commission rate is decreased, a possible function is:

This is so, because 0.05 is less than 0.1
So, the possible functions in the two scenarios are:
and 
See attachment for the graphs of both functions

Factors of 3771 are:
1, 3, 9, 419, 1257, 3771
Factors of 3298 are:
1, 2, 17, 34, 97, 194, 1649, 3298
As you can see, no factors goes into both number.
Therefore, there should be no number goes into both 3771 and 3298 evenly.
Hope this helps and hope I didn't misunderstood this question. :D
Slope: (y2-y1)/(x2-x1)
(-3+2)/(-1+1) = -1/0 = undefined
The slope is undefined
