We draw the number line for each inequality

<=============o------------------------------     for x < -3
 -7 -6 -5 -4 -3 -2 -2  0  1  2  3  4  5  6  7 

-----------------------------o===============>    for x > 2
 -7 -6 -5 -4 -3 -2 -2  0  1  2  3  4  5  6  7 

Since it's "or" we put both together on a number line:

<=============o--------------o===============>    for x > 2
 -7 -6 -5 -4 -3 -2 -2  0  1  2  3  4  5  6  7
