Answer:
n=5/3
Step-by-step explanation:
In order for the two lines to be perpendicular the slopes have to be flipped and so do the signs so the slope of the unknown value has to be -1/3
all you do is -1/3+2=5/3
5/3-2=-1/3 which make the two lines perpendicular
sorry if this doesnt make sense its hard to explain it virtually
