Answer 5

the way we did it before graphics (yes, I am that old)
solve for Y=5 and print a '*' there and at X=0
repeat down to 1
draw a line of '*'s
then do Y=-1 on down to -5
so you end up with something like this:
* *
* *
* *
**
***************************

well, you get the idea... hope it helps

Answer 7

The C programming language does not have any built-in capabilities for drawing lines (or anything, for that matter). You need to use some kind of graphics library, such as OpenGL (among many many others).

SInce you implicitly ruled out "using graphics header" (which I, as well as philips13, interpreted to mean that you're not allowed to use a graphics library---which are typically linked to your program via some sort of header), printing characters is pretty much the only option you have, so philips13 is right.

Or perhaps we both misunderstood your requirements; perhaps you can clarify them?

If you are not allowing any libraries, in principle the only way to draw proper lines is by "talking" directly to the hardware. If you have a half-way modern operating system (i. e. you are not using an embedded device or a computer from the 80s or before) that is also out of the question.
