I hope I understood the question correctly...
You could draw a box on the coordinate plane with verticies (0,0) (5,0) (0,5) (5,5) and then draw the line y= (5x-1)/4. Then you shade the appropriate area (which is bounded by the box).
thanks for reply, but im still having trouble being able to draw the actual line :s

y= (5/4)x-1/4
this is our equation. Try to pick two nice x values (they can even be outside the box, it doesn't matter) and simply connect them. Try 4, for example.

Actually 1 and 0 work better
