Graph the system of inequalities

x¡Ü2
y¡Ý-2x+4

I am having trouble understanding what points to plot on the graph and also how the graph should be shaded (if at all).

I am not familiar with this notation at least the way it is coming up on my screen.

Graph the system of inequalities

x (lesser or equal to sign)2
y (greater or equal to sign)-2x+4

I am having trouble understanding what points to plot on the graph and also how the graph should be shaded (if at all).

You probably mean < or > or ≥

If you can't generate these symbols, then use "words" to describe your relation

BTW, to get ≥ I hold down the Alt key while at the same time hitting 242 on the number pad of my PC running Windown XP

you can experiment with that starting with
Alt 1 to get ☺

Well, first see what happens when x = 2
then y ≥ -4+4 so y ≥ 0
so the point (2,0) is at your upper x point and all y above that
Now what happens for a smaller x, such as x = 0?
if x = 0 then y≥4
so the point (0,4) is included and everything above that point.
Now I am going to go out on a limb and say everything above the line y=-2x+4 and to the left of the vertical line x = 2 is in your territory including the lines at the edges
