Question 44068
y - 3x < -4
Rearrange to give in the form of a line equation "y=mx+c" but note that the "=" should be replaced with "<" here.
y  < 3x -4
Now the inequality is satisfied whenever y is below the line "y=3x-4" i.e. below the line on this graph:
{{{ graph( 300, 200, -10, 10, -15, 15, 3x-4) }}} 

I hope this helps 
P.S. I am trying to start up my own homework help website. I would be extremely grateful if you would e-mail me some feedback on the help you received to adam.chapman@student.manchester.ac.uk
