Question

Consider the line L(t)=⟨3t−1,4+2t⟩ . Then:
L is (parallel/perpendicular/neither) to the line ⟨1+6t,5−9t⟩
L is (parallel/perpendicular/neither) to the line ⟨4.5t−5,3t−3⟩

L is (parallel/perpendicular/neither) to the line ⟨5−6t,−1−4t⟩
L is (parallel/perpendicular/neither) to the line ⟨5−4t,1+6t⟩

Answer 1

what's the vector along L(t)?

Answer 2

any idea?

Answer 3
