You can put this solution on YOUR website!
system%28a%3E=6%2Br%2Ca%2Br%3E18%29


system%28r%3C=a-6%2Cr%3E-a%2B18%29


If r is for vertical axis and a is for horizontal axis, then you can graph the reference lines and identify points that satisfy the inequality system.


This is just to show the reference lines; not the plot for the inequalities:
graph%28400%2C400%2C-2%2C20%2C-2%2C20%2Cy=x-6%2Cy=-x%2B18%29
