Which system of linear inequalities represented by the graph y_> 2x-1 and y_< 2x+2

1. Check picture 1.

2. By drawing 2 pairs of points,as shown in the picture, we can easily draw the lines y=2x-1 and y=2x+2

3. We notice that the lines are parallel. (we can notice this also from the slopes of the lines, that is the coefficients of x'es, both equal to 2, which means the lines are parallel)

4. Pick (1, 3), as shown in the picture to check which side of each line we will color. (any point can work.)

5. Check (1, 3) in inequality  y_<2x+2: 
3_<2*1+2=4 is actually true, so we color the part of the line containing (1, 3) 

Check (1, 3) in the inequality y_>2x-1: 3_>2*1-1=1 which is true, so we color the part of the line containing the point:

6. So we color the part below the black line and the part above the blue line.

The solution is the part colored in both cases, which is the strip between the lines.

7. picture 2 is the graph of the system of inequalities
y_>2x-1 and y_<2x+2

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
