F(n) = 5n + 6 find a solution (n, f(n)) for the function if the independent variable has a value of -2.

   n = -2 ;  F(n) = - 4.  So, written as: "(n, (f(n))" ;  
                                                                  the answer is:  "(-2, -4)" .

Explanation: 


n = -2  (given);

F(n) = 5n + 6 .

F(-2) = 5(-2) = 5*(-2) + 6 = -10 + 6 = - 4 .
