amistre64 · Answer

your not not wrong :)

anonymous · Answer

perpendicular

amistre64 · Answer

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

amistre64 · Answer

since 1*-1 = -1  these are perps

anonymous · Answer

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

amistre64 · Answer

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

so perpendicular?
