i chose None of these ..am i right?

OpenStudy (amistre64):

your not not wrong :)

OpenStudy (anonymous):

perpendicular

OpenStudy (amistre64):

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

OpenStudy (amistre64):

since 1*-1 = -1 these are perps

OpenStudy (anonymous):

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

OpenStudy (amistre64):

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

OpenStudy (anonymous):

so perpendicular?

OpenStudy (anonymous):

Is it peeerrrrpppeeennndddiiiccccuuullaaaarrr?
