Question 44088
Rearrange so you have just y on the left hand side:
{{{y>(1/2) x -2}}}
The solution occurs at any point above the graph y = (1/2)x - 2

Shade the region above the graph to show your solution graphically.

{{{ graph( 300, 200, -10, 10, -10, 10, (x/2)-2) }}} 

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
