1. Problem Description

The problem asks to graph the solution of the following system of inequalities:
y2xy \ge -2x
y4x+3y \ge 4x + 3

2. Solution Steps

To graph the solution to this system of inequalities, we first consider each inequality separately.
For the first inequality, y2xy \ge -2x, we graph the line y=2xy = -2x. This line passes through the origin (0,0)(0,0) and has a slope of 2-2. Since the inequality is y2xy \ge -2x, we shade the region above the line.
For the second inequality, y4x+3y \ge 4x + 3, we graph the line y=4x+3y = 4x + 3. This line has a yy-intercept of 3 and a slope of

4. Since the inequality is $y \ge 4x + 3$, we shade the region above the line.

The solution to the system is the region where the shaded regions of both inequalities overlap. The lines y=2xy=-2x and y=4x+3y=4x+3 intersect where 2x=4x+3-2x=4x+3, which implies 6x=36x=-3, so x=12x=-\frac{1}{2}. When x=12x = -\frac{1}{2}, y=2(12)=1y = -2(-\frac{1}{2}) = 1. Therefore the two lines intersect at the point (12,1)(-\frac{1}{2}, 1).

3. Final Answer

The solution to the system of inequalities is the region above both lines y=2xy = -2x and y=4x+3y = 4x + 3. The intersection point of the two lines is (12,1)(-\frac{1}{2}, 1).
