Sure! Here's an example of a system of two linear inequalities:
- \(2x + 3y < 6\)
- \(x - y \geq 1\)
Graphing the System
-
To graph these inequalities, you would first graph the corresponding equations:
-
For \(2x + 3y = 6\), you can find the intercepts. The x-intercept occurs when \(y = 0\): \[ 2x + 3(0) = 6 \implies x = 3 \quad \text{(point (3,0))} \] The y-intercept occurs when \(x = 0\): \[ 2(0) + 3y = 6 \implies y = 2 \quad \text{(point (0,2))} \] This line is dashed because the inequality is strict (\(<\)).
-
For \(x - y = 1\), the x-intercept occurs when \(y = 0\): \[ x - 0 = 1 \implies x = 1 \quad \text{(point (1,0))} \] The y-intercept occurs when \(x = 0\): \[ 0 - y = 1 \implies y = -1 \quad \text{(point (0,-1))} \] This line is solid because the inequality is non-strict (\( \geq \)).
-
Solution Region
The solution to the system of inequalities consists of the points that satisfy both inequalities simultaneously. You would shade the appropriate regions for each inequality on the graph.
- For \(2x + 3y < 6\), shade below the dashed line.
- For \(x - y \geq 1\), shade above or on the solid line.
The overlapping shaded region represents the solution set for the system of linear inequalities.
