Use www.wolframalpha to plot the first condition
http://www91.wolframalpha.com/input/?i=3x+%2B+1+%3C%3D+-2
Thne use it again to plot the second one
http://www91.wolframalpha.com/input/?i=+2x+%2B+3+%3E%3D+5
Since the problem said "OR", then from your logic course, you know that x OR Y is true when either x or Y is true. So the resulting plot is the Union of the two plots above (any x that works in either equation, is a valid answer)
