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).

Graph the system of inequalities

x (lesser or equal to sign)2

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

**Reiny**, Monday, May 26, 2008 at 4:38pmYou 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 ☺

**Damon**, Tuesday, May 27, 2008 at 5:56pmWell, 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
