How do you graph the inequality y = -3 |x + 2| -1

Hello : 
y = -3 |x + 2| -1
 2 cas : 
 1 )  x+2 ≥ 0 ;  |x + 2| = x +2
so : x ≥ -2  : y = -3 (x+2) -1
conclusion : y = -3x-7  when : x ∈ [-2 ; +∞[(two values of x in this itervall  you have the graph)
2 )  x+2  ≤  0 ;  |x + 2| = - (x +2)
so : x ≤ -2  : y = -3 (-(x+2) ) -1
conclusion : y = 3x+5  when : x ∈ ] -∞ , -2 ] (two values of x in this itervall  you have the graph)
look the graph :
