If a line has a slope of m=1/2, find the slope of a line parallel & a line perpendicular to it.

Question

anonymous · Answer

parallel lines always have same slope

for two perpendicular lines, the multiple of their slope is -1
so if one line has slope m, and a line perpendicular to it has slope n then m*n=-1

anonymous · Answer

that didn't really help with perpendicular part like i understand the parallel but thats it

anonymous · Answer

ok , so its given that a line has a slope -2/3
suppose the line perpendicular to it has slope x

so (-2/3)*x=-1

x =3/2 will be the slope of the other line

anonymous · Answer

is x always going to = -1?

anonymous · Answer

no when you multiply the slopes of the two lines, that are perpendicular , you get -1
