Perpendicular means that the slopes will be opposite reciprocals. So if the slope of the red line is 4, then you have to swap that and make it a negative. Instead of it being 4/1 it will now be 1/4. Then you just add the negative and boom, you got the slope of the green line.

TETSXPREME:

MusicGeek:

Yeah. It would be D.
