LOOK AT THIS AND ANSWER THIS QUESTOIN THANK YOU!
 
Which system is represented by the graph?
   y ≥ - x - 1
y < 2x + 2 
   y ≤ -x + 2
y < 2x - 1
 
   y < - x - 1
y ≥ 2x + 2 
   y > - x + 2
y ≤ 2x - 1

Lets look at the line sloping upward. The slope is the change in the y divided by the change in the x. It's pretty simple to see that the slope is 2, and the y intercept is 2, so one of the equations is y=2x+2. Since it's shaded above the line, it must be 
$$y \ge 2x +2$$ Now try this for the second line.
