Answer: 
B. (-2,-4)
Explanation
Given equations: 
    y = 3x + 2 
    y = -2x - 8 
Solving both equations will yield the values of x and y; 
Solution: 
    y = 3x + 2    ----- (i)
    y = -2x - 8   ------ (ii)
Using substitution method, input equation i, into ii
     3x + 2 = -2x - 8
Collect like terms and solve;
      3x + 2x = -8 -2 
          5x  = -10 
             x  = -2
Then put x = -2 into i, to find y
       y = (-2 x 3) + 2
        y = -6 + 2 = -4
So, the solution of the equation is B. (-2,-4)
