Math Problem Statement
Graph the following system of inequalities on the set of axes below:
-2y < 3x + 12
x ≥ -3
Solution
The inequalities provided in the image are:
Let's break these down step by step:
First inequality:
- To graph this, we need to first convert the inequality into slope-intercept form, which is .
- Divide both sides by (note that when dividing by a negative number, the inequality sign reverses):
- The line corresponding to this inequality is . Since the inequality is "greater than" (not equal), we will draw a dashed line to indicate that points on the line are not included in the solution.
- The region above the line is the solution region for this inequality.
Second inequality:
- This represents a vertical line at , with shading to the right of the line (since ).
Graphing Procedure:
- Graph the dashed line .
- Shade the region above the dashed line.
- Draw a solid vertical line at and shade to the right of it.
Solution Set :
- The solution set is the region where the shading from both inequalities overlaps. This is the area that satisfies both conditions.

Tip: When graphing inequalities, always start by sketching the boundary line and determine whether to use a dashed or solid line, then decide which side to shade!
