Math Problem Statement
Graph y is less than or equal to x - 2 as a system of linear inequalities.
Solution
To graph the inequality as a system of linear inequalities, we first need to understand that this inequality involves a boundary line and a shaded region.
Step 1: Graph the Boundary Line
The inequality includes the line , which is a linear equation with a slope of 1 and a y-intercept at -2. This line will be solid (not dashed) because the inequality is "less than or equal to," meaning points on the line satisfy the inequality.
- Start by plotting the y-intercept at (0, -2).
- Use the slope (1) to find another point by moving up 1 unit and right 1 unit.
- Draw a solid line through these points.
Step 2: Determine the Shaded Region
Since the inequality is , we shade the region below the line, as that represents all points where is less than or equal to .
Representing as a System of Inequalities
If you're instructed to show this as a "system," we could interpret that as potentially adding a restriction on the domain or range. Without additional constraints, however, the inequality alone defines the region.
Would you like me to delve deeper into creating a system with multiple inequalities, or do you have any specific questions about graphing this?
