Question 214797
Why the line x=4 is a vertical line? How do begin? How do I solve this?
------------------
Any line can be graphed if you can find two points on the line.
-------
Two points on your line would be (4,0) and (4,5)
-------
Plot those two points on a coordinate system.
Draw a line thru them.
Notice that the line passes thru all the points where x = 4.
Notice that the line is perpendicular to the x-axis.
Notice that the line is vertical.
