Do you know what to do? I am confused.

kobeni-chan · Answer

Slope-intercept form is written as y=mx+b, with m=slope and b=y-intercept
Since the lines will be perpendicular, I think the slope for the second line should be the reciprocal of the given line's slope.

anonymous · Answer

okay so the blue line's slope is 3x

kobeni-chan · Answer

The slope for the line given is 3, so the slope for the line you're looking for should be 1/3

kobeni-chan · Answer

yeah

anonymous · Answer

wouldnt it be -1/3 because it's the opposite reciprocal

kobeni-chan · Answer

yes sorry I just realized that

anonymous · Answer

the only option with the opposite reciprocal on my paper is  y = -1/3x + 4

anonymous · Answer

would this be the right answer?

kobeni-chan · Answer

I used a graphing program GeoGebra to graph that (y=(-1/3)x+4, and that is right :)

anonymous · Answer

would it be y=-3x-16?

anonymous · Answer

okay thanks!

kobeni-chan · Answer

No problem! :) I would also recommend that GeoGebra program if you have a computer and are taking any Algebra or Geometry classes. It's free and I'm sure you can google where the site to download it was c: it's been tons of help for me

ive heard about it but never tried it out for myself!
