To find the y-intercept of  7x + 2y  =  -12, replace the x-term with 0:

     7x + 2y  =  -12     --->     7(0) + 2y  =  -12     --->     0 + 2y  =  -12     --->     2y  =  -12      --->     y  =  -6

 

To find the x-intercept of  -3x - 5y  =  21, replace the y-term with 0:

     -3x - 5y  =  21     --->     -3x - 5(0)  =  21     --->      -3x - 0  =  21    --->      -3x  =  21     --->     x  =  -7

 

Projected profit  =  projected revenues - projected costs

Projected profit  =  (3x + 22,050) - (2x - 1,560)

                          =  3x + 22,050 - 2x + 1,560

                          =  x + 23,610
