Answer 1

If you rewrite the first equation, you will see that it becomes

$x = y + 4 \to y = x - 4$

i.e. exactly the second equation. This causes the system to be underdetermined, since you're asking for the points of intersection of a line with itself, which means all the points of the line.

To graph it, you should graph twice the line $y = x - 4$. To draw it, sample any two points and connect them. For example, choose $x = 4$ and $x=5$ to get, respectively, $y=0$ and $y=1$. Then, draw the points $(4,0)$ and $(5,1)$ and connect them.
