Not sure if this is the right header for this, but please help if you can.
Question: Explain why the line x = 4 is a vertical line.
The line x = 4 tells me that the value for x in the form (x,y) does NOT change.
While the value for y will include DIFFERENT values.
This line is vertical at the point x = 4 and y = 0, which looks like this
(4,0).
If you were to travel UP or DOWN on the line x = 4, the value of x will remain 4 while the y changes in value.
I hope this helps.
