Math Problem Statement
Solve each system of inequalities by graphing. y - x < 3, y - x ≥ 2
Solution
To solve the system of inequalities by graphing, we'll graph each inequality and find the region where the solutions overlap. Here are the steps:
Inequality 1:
- Rewrite the inequality in slope-intercept form (i.e., ):
- Graph the boundary line . This line will have a slope of 1 and a y-intercept of 3.
- Determine the region to shade: Since the inequality is , shade the region below the line.
Inequality 2:
- Rewrite the inequality in slope-intercept form:
- Graph the boundary line . This line will also have a slope of 1 and a y-intercept of 2.
- Determine the region to shade: Since the inequality is , shade the region above the line.
Graphing and Finding the Solution
- Graph both boundary lines:
- (dashed line, because the inequality is strict)
- (solid line, because the inequality is inclusive)
- Shade the appropriate regions:
- Below the line
- Above the line
- Identify the overlapping region: The solution set is the region where the shaded areas overlap.
Solution
The solution is the region between the lines and , where:
- (below the dashed line)
- (above the solid line)
This region forms a strip parallel to the lines, above and below .

Tip: When graphing inequalities, always pay attention to whether the boundary line should be dashed or solid—this indicates whether the line itself is part of the solution set.
