the slope of perpendicular line segments are 1/2 and d/3, what is the value of d? A. d=-6 B. d=-3/2 C. d=3/4 D. d=6

OpenStudy (jskinny0831):

i did cross division and got 1.5 so would it be 3/2?

OpenStudy (jskinny0831):

can you help? @ggdvaaa

OpenStudy (jskinny0831):

can you please help me? @DanJS

OpenStudy (danjs):

yeah, the slopes of two perpendicular lines are , m and -1/m

OpenStudy (danjs):

the given one is 1/2 , so flip it over and change the sign, that is what the other one should be

OpenStudy (jskinny0831):

okok so we have a slope of -2 and i multiply 3 on both sides and i get -6?

OpenStudy (danjs):

right

OpenStudy (jskinny0831):

okay perfect thank you so much
