1. Problem Description

The problem asks to find the solution set of the following system of inequalities and graph it.
y2xy \ge -2x
y3x+2y \ge 3x+2

2. Solution Steps

First, we graph the line y=2xy = -2x. This is a line with slope 2-2 and yy-intercept 00. Since the inequality is y2xy \ge -2x, we shade the region above the line.
The line is included in the solution, so we draw a solid line.
Next, we graph the line y=3x+2y = 3x + 2. This is a line with slope 33 and yy-intercept 22. Since the inequality is y3x+2y \ge 3x + 2, we shade the region above the line.
The line is included in the solution, so we draw a solid line.
The solution to the system is the region where the shadings of both inequalities overlap. This is the region that is above both lines y=2xy = -2x and y=3x+2y = 3x + 2.
To find the intersection point, we set the two equations equal to each other:
2x=3x+2-2x = 3x + 2
5x=2-5x = 2
x=25x = -\frac{2}{5}
Then, y=2(25)=45y = -2(-\frac{2}{5}) = \frac{4}{5}
So the intersection point is (25,45)(-\frac{2}{5}, \frac{4}{5}).

3. Final Answer

The solution is the region where y2xy \ge -2x and y3x+2y \ge 3x + 2. This is the area above both lines, and the lines are included in the solution set. The two lines intersect at the point (25,45)(-\frac{2}{5}, \frac{4}{5}).
