Question 436897: How would I solve this problem?
Graph the solution set of the system of inequalities or indicate that the system has no solution.
-x + 2y < -6 (This less than symbol is underlined.)
3x + 2y > - 18
I know that shading would be involved but how does it look like graphed?
Thank you very much for your help.

You can put this solution on YOUR website! solving these as equations (instead of inequalities) shows where the "boundary" lines are for the system
-x + 2y < -6 crosses the x-axis at (6,0) and crosses the y-axis at (0,-3)
___ it is a solid line (less than or equal to) and the shading would be below the line
3x + 2y > - 18 crosses the x-axis at (-6,0) and crosses the y-axis at (0,-9)
___ it is a dotted line and the shading would be above the line
the lines intersect at (-3,-4.5) and divide the x-y plane into 4 wedges
___ since the solution area is above one line AND below the other , the shaded area should be the wedge to the right
