4x + y< 2
y> -2
graph the solutions to a linear equality in two variables as a partial plan

The two inequalities can be rewritten as

The solution is composed by every point below the graph of the line , and above the horizontal line

To draw the line we can build a little table (only 2 points are required):

So, if you draw the points (0,2) and (1, -2) and connect them, you'll have your line.

To draw the line , simply pick any point with y coordinate -2, for example (0, -2), and draw a horizontal line.

Choose the above/below areas as specified above to solve the system.
