Matricies 3 D

Question 1

If they are parallel how to tell

If same then how to tell

Answer 1

If the normal vecotr coeffeicmt dare kurlitples of another

If the whole equation is the same

Question 2

If the determinant is zero, it means there is a solution

If det is not zero then what

Answer 2

Either form a triangular prism , THIS IS WHEN NITHIGN CSN AHOOEN

Or a sheaf , this is when two CONSISTENT EQUATIONS CAN BE MADE OF ONE ANOTHER . This is INFINITE SOLUTIOSN

This is assuming not parallel at all
