+x+=+4+ is a vertical line where, no
matter what +y+ is, +x+ always
equals +4+
It's not a function, but you can find it's
intersection with:
+2x+-+y+=+2+
+y+=+2x+-+2+
+x+=+4+
---------------
+y+=+2%2A4+-+2+
+y+=+8+-+2+
+y+=+6+
The intersection is at ( 4,6 )
----------------------------
For graphing +y+=+2x+-+2+
+x+=+0+
+y+=+-2+
-------------
+y+=+0+
+x+=+1+
