perpendicular

parallel have the same slope; these do not perps have the property that slope*slope = -1

since 1*-1 = -1 these are perps

perpendicular as the slope is the negative inverse in the two lines!!!

another way to view it is if the dot product of the vector of the slopes =0 then they are perps 1, 1 -1, 1 ----- -1+1 = 0 ; they is perped
