Explanation:

First, draw the lines without < or > signs, just use equals signs:

3x + y = -3

y = -3x - 3 (slope of -3, y-intercept at (0,-3) )

x + 2y = 4

2y = -x + 4

y = -(1/2)x + 4

Now shade the region above and including line (1) and below and including line (2).

Note for similair problems: If you have to multiply or divide by a negative number when solving for y, remember to flip the < or > sign to the other one when determining where to shade on the graph.
