vty stands for virtual terminal; it is used for connections such as Telnet or the safer SSH. The numbers 0 1 refer to a range of possible connections. Usually all possible connections on a router or switch should be programmed together, since you don't have control over which user accesses which connection.
by zero line do you mean 0? or do you mean 0 with the slash in it like this /?
If you mean points of (2, 1) and (0, -5) then the slope of the line is 3
If you mean points of (3, 1) and (0, -5) then the slope is 2
If you mean points of: (-3, 9) and (0, 0) then the equation works out as y = -3x
If you mean points of (7, 2) and (0, 0) then the equation is y = 2/7x

telnet
The router can handle as many telnet sessions as there are VTYs. The maximum number of possible VTYs varies by platform. There are 5 VTYs by default, you can add more VTYs by configuring them in configuration mode. Example Line vty 0 16 login (or any command) Once you refer to a VTY, it will be created.
