Question

Consider the line 2x-4y=8.

What is the slope of a line perpendicular to this line?

What is the slope of a line parallel to this line?

alexandervonhumboldt2 · Answer

perpendicular lines have negative reciprocal slopes
parallel line have same slopes

anonymous · Answer

Wait really, so what wuold I have to do?

alexandervonhumboldt2 · Answer

first find slope of your line

anonymous · Answer

wait would it be for the perpindicular -- >-8
and for the paralell it would be 8?

alexandervonhumboldt2 · Answer

2x-4y=8.
-4y=8-2x
y=(-2x+8)/(-4)=1/2x-2

the slope of your given line is 1/2

alexandervonhumboldt2 · Answer

the slope if 1/2.

the negative reciprocal to 1/2 is -2.

anonymous · Answer

so just to reiterate, the perpidicular would be -2 and the parellel would be the same?

yes

no problem :P
