1. Problem Description
The problem asks us to graph and shade the solution region for the following system of inequalities:
2. Solution Steps
First, let's consider the first inequality: .
To graph this, we first treat it as an equation: .
We can find the x-intercept by setting : , so .
We can find the y-intercept by setting : , so .
Thus, the line passes through and .
Since the inequality is , we draw a solid line.
To determine which side to shade, we test the point : simplifies to , which is false. Therefore, we shade the region that does *not* include .
Now, let's consider the second inequality: .
To graph this, we first treat it as an equation: .
The y-intercept is . The slope is , so for every 2 units we move to the right, we move 3 units up.
Since the inequality is , we draw a dashed line.
To determine which side to shade, we test the point : simplifies to , which is false. Therefore, we shade the region that does *not* include .
The solution region is the intersection of the shaded regions for both inequalities.
3. Final Answer
The solution is the graph with a solid line through (5,0) and (0,-4) shaded to the side that does not contain the origin and a dashed line for with a y intercept of -2 shaded above the line. The solution is the overlapping shaded region.
