You can put this solution on YOUR website! 32): Could you please help me to understand graphing inequalities? :]
------
The thing to understand is that you NEVER graph
inequalities directly. You graph the boundary
of the inequality, which is always an equality.
-----
To graph y < 3x+2 you 1st of all graph
y = 3x+2 as a dashed line. That is the
boundary of the two inequalities: y < 3x+2
and y > 3x+2.
------
You want y is LESS than the boundary so you
should shade the half-plane BELOW the boundary.
That is the graph of the inequality.
