Question 134363
y>= -10/7x+10 y is less than or equal to negative ten over 7x plus ten
{{{graph(400,300,-10,10,-10,10,-10/(7x+10))}}}
This is the graph of the EQUALITY.  Since you also want y GREATER you
need to shade the area ABOVE this boundary curve.
==============================================================
y>= -9/8x+17/8 y is less than or equal to negative 9 over 8x plus 17 over 8 
{{{graph(400,300,-10,10,-10,10,-9/(8x+(17/8)))}}}
This is the graph of the EQUALITY. Since you also want y LESS you need
to shade the area BELOW this boundary curve.
----------------------------------------------------------------
y<= -11/7x+18/7 y is greater than or equal to -11 over 7x plus 18 over 7 
{{{graph(400,300,-10,10,-10,10,-11/(7x+(18/7)))}}}
This is the graph of the EQUALITY. Since you also want y LESS you need
to shade the area BELOW this boundary curve.
=======================================================
y<= -2x+3 y is greater than or equal to negative 2x plus 3. 
{{{graph(400,300,-10,10,-10,10,-2x+3)}}}
This is the graph of the EQUALITY. Since you also wnat y LESS you 
need to shade the half-plane BELOW this boundary line.
