What does it mean when a question asks: "Solve each system by graphing?"

Then:

A) y > .5x - 2

3x + 4y<6

B) 4x-y <= (less than or equal to) 8

y <= (less than or equal to) 5

x + 3y >6

I'm confused as to how to graph these and why it should be solved like that.

I understand the steps are:

1. Isolate for y. (I can't remember about the rule where it switches from > to <. If anybody remembers, please let me know!)

2. Graph.

3. Color it in. < Confusing...
