Math Problem Statement
Graph the solution of the system of linear inequalities: 2x + y ≤ 4, x ≥ -5, y ≤ 3.
Solution
Let's analyze the system of linear inequalities given in the image:
- First inequality:
- Second inequality:
- Third inequality:
Steps to graph the solution:
-
Graph the boundary line for :
- First, find the intercepts.
- x-intercept: Set in , giving .
- y-intercept: Set in , giving .
- Draw the line passing through the points and .
- Since the inequality is , shade the region below this line.
- First, find the intercepts.
-
Graph the boundary for :
- This is a vertical line at .
- Since the inequality is , shade the region to the right of this line.
-
Graph the boundary for :
- This is a horizontal line at .
- Since the inequality is , shade the region below this line.
-
Find the region of overlap:
- The solution to the system of inequalities is the region where all three shaded areas overlap.
