I'm not sure how to display a graph on here, so I'm afraid I can't help you with that part.

However, the answer is C. (-2,3).

To create the graph, either put it into a graphing calculator or manually graph the equations by plugging in different numbers to the equation.

Answer:

A.  v= $3,995.72 - $1,838.03

Step-by-step explanation:

Given:

fixed expenses: $1,838.03

total expenses: $3,995.72

We need to find the amount of Variable expense (v).

Now We know that;

Variable expense (v) can be calculated by Subtracting Fixed expense form Total expense.

framing in equation form we get;

Variable expense (v) = total expenses - fixed expenses.

Variable expense (v) = $3,995.72 - $1,838.03 = $2,157.69

Hence The equation represents Jessie's variable expense (v) = $3,995.72 - $1,838.03

So you would make this equation 

2x+3x=60
        5x=60 
               x=12
                     smaller=24
                     larger=36
