OK here is the question.(adsbygoogle = window.adsbygoogle || []).push({});

Find an equation of the plane that contains the lines given by

(x-1)/-2 = y = z+1

and

(x+1)/-2 = y-1 = z-2

This is what I did.

I found 2 points for the first line and 2 points for 2nd line

A= (0 , 0.5, -0.5)

B=(1 , 0 , 1)

C= (0, 0.5, 1.5)

D= (1, 0, 1)

then i got their vector equations

AB = <1, -0.5, 1.5>

CD = <1, -0.5, -0.5>

What now? Do i get their cross product? I did cross product and ended up with x+2y = 1
