It depends on which direction you want.

 

[ttpp1124]

The question states "A line passes through the points M(4, 5) and N(9, 5). Determine vector and parametric equations for this
line."

So it's M to N? Meaning M-N?

Does a line have a direction?

Does a line have a direction?

No, not always

 

[PeroK]

No, not always

In this case you get to choose, right? You can choose to describe the line from $M$ to $N$ or from $N$ to $M$.

Ok, thank you
