.
Treat this as you would an equation and solve for Y by subtracting 6 from both sides.
The result is:
.
.
Graph this equation by making a graph of the equation Y=4. No matter what value X is, the
value of Y is always +4. This graph is a horizontal line that goes through +4 on the Y-axis
and runs infinitely far in both the positive and negative direction.
.
Notice that the equation
tells you that the value of Y must at least equal
but can be above this line. You can shade in everything above the graphed line and just
including this line at the bottom of the shading, and the shaded area will be the region
where the value of Y can be.

Hope this helps you to understand the problem a little better.
