Question

Hello ^___^
Please help me! Thank you very very much!

Determine if the planes are parallel.

[x,y,z] = [1,2,2] + s[0,-1,0] + t[0,0,1]

[x,y,z] = [1,0,-3] + s[0,0,1] + t[-1,0,0]

thank you ^__^Y

Answer 1

Find a normal to the first plane, and a normal to the second plane.
If the two normals are scalar multiples of each other, then the planes are parallel.

or

try to find their intersection, if you can find a solution, then they are obviously not parallel
