Answer:
The answer to your question is:  x = -1
Step-by-step explanation:
Data
slope of l = x
slope of m = x +2
they are ⊥
Process
If they are ⊥, then,     x + 2  = - 1/x
                                   x(x + 2) = -1
                                   x² + 2x = -1
                                   x² + 2x + 1  = 0
                                  (x + 1)² = 0
                                  x + 1 = 0
                                 x = -1
