# How do you graph y - 4 < x - 6?

$y - 4 = x - 6 \setminus \iff y = x - 2$.
This is the equation of a line, which you can easily graph. If you think about it, the graph of a function is the set of the points which satisfy the relation $y = f \left(x\right)$; but we are looking for the points which satisfy the relation $y < f \left(x\right)$.
You can see that the two requests are strongly related: if the graph of the line is the set of points in which $y = x - 2$ holds, the set of points in which $y < x - 2$ holds is the part of the plan below the graph, as you can see:
