You can put this solution on YOUR website! y<=2x
2x+3y<=0
note that the first equation is solved for y, now we solve the second equation for y
3y <= -2x
y <= -2x/3
now we graph both inequalities
the shaded area is where the inequalities overlap
now let's look at the x values from each inequality
x >= y/2 from first equation
x <= -3y/2
we can combine the two inequalities
y/2 =< x <= -3y/2
