Question 102214
Can you please help me graph x>2y on a coordinate plane?
-------------
Solve for y: 
y<(1/2)x
--------------
Graph the line y=(1/2)x as a dashed line thru the points (0,0), (2,1)
That is the boundary of the solution of your problem
Darken all the points where y<(1/2)x that is all the points that are
below the line.  That would be the half-plane below the boundary line.
================
{{{graph(400,300,-10,10,-10,10,(1/2)x,(1/2)x-1,(1/2)x-2,(1/2)x-3)}}}
Cheers,
