Answer:

Step-by-step explanation:

This can be reduced to the equivalent form 3y - 2x = -21 by dividing each term by 4.  

3y - 2x = -21 can be solved for y in terms of x as follows:

       

      2x - 21

y = -------------      This is a linear function.

           3

Likewise, 3y -2x = -21 can be solved for x in terms of y.
