Can you please confirm my below understanding, if it is right or wrong?

1. If a line in a plane is directed in a north-east direction it will have a positive slope.
2. if a line in a plane is directed in a south-east direction it will have a negative slope.
3. If a line is parallel to y-axis the slope is not defined.
4. If a line is parallel to x-axis the slope is zero.
If you cant explain it simply you dont understand it well enough!!!
