Find the normals to the curve
xy + 2x - y = 0 that are parallel to the line 2x + y = 0.
I can find the normal lines and the slope but I don't know what I'm suppose to do with the line 2x + y = 0

The question requires that among the family of normals to the curve, those parallel to the given line are required, that is where 2x+y=0 come in.
y=1x/2-4/3
