Hi,
Just wanted to clarify with parameterising.
So for a straight line, connected from the point $z_1$ to $z_2$
We can use the formula
$ (1t)z_{1} + z_{2}t$ or
$ z_{1} + t[(z_1  z_2)]$
I am just wondering, does it matter which end points you allocate to be z1 and z2?
if so, in which manner do we go about assigning the points?
So if you could look at the attached image, for the line $y_3$
could someone please give me what the correct $z_1$ and $z_2$ would be? I've tried both, but can't seem to get the answer.
I did also notice that the direction of the line is going from right to left, so what does that change for us, is it a negative direction?
I am confused why the parameter is ranging from 2<t< 0, although i suspect it may be because the arrow is pointing from right to left.
Any help is very much appreciated.
