Correct option is (B) -2
Given line is 2x+y+4 = 0
\(\Rightarrow y=-2x-4\)
By comparing with y = mx+c, we obtain \(m=-2\)
\(\therefore\) Slope of the line 2x + y + 4 = 0 is m = -2.
\(\therefore\) Slope of line parallel to line 2x+y+4 = 0 = Slope of line 2x+y+4 = 0
= -2
Hence, the slope of the line parallel to the line 2x+y+4 = 0 is -2.
