divide by 12
and then write in the form
$$\frac{ x }{ a }+\frac{ y }{ b }+\frac{ z }{ c }=1$$
here a,b,c are the intercepts

anonymous · Answer

@surjithayer So I would divide 2x – 3y + 4z =12 by 12? Im confused...

Sorry, Im really horrible at geometry

@Juan21 Do you get it?

anonymous · Answer

Im working on it

anonymous · Answer

@Juan21 Okay thanks :)

anonymous · Answer

I think the answer is (6,0,0) (0,-4,0) (0,0,3)

anonymous · Answer

@Juan21 Could you show me how you got that? I was trying to solve it before and had gotten the (6,0,0) answer for one of them but my other two were different. I probably did something wrong so could i compare ours?

anonymous · Answer

Sure. So to find the intercepts you plug in a zero for the other variables. For example, to find the y intercept you     2(0)-3y+4(0)=12------->     -3y=12, divide by -3,----->      y=-4

@Juan21 Ohhh I see what I did wrong! Thanks so much!
