Key Concepts

Graphical Representation of Inequalities

This concept involves depicting inequalities on the coordinate plane by plotting the boundary (using a solid line for inclusive inequalities or a dashed line for strict ones) and shading the region that satisfies the inequality. It is a fundamental aspect of translating algebraic inequalities into a visual context to understand the set of solutions.

Systems of Inequalities

Systems of inequalities involve more than one inequality that must be satisfied at the same time. The solution to the system is found by graphing each inequality separately and identifying the region where the shaded areas overlap, representing the set of points that satisfy all the conditions simultaneously.

Quadratic Inequalities in Two Variables

Quadratic inequalities in two variables typically represent conic sections, such as circles, ellipses, parabolas, or hyperbolas. The inequality often defines a filled area (inside or outside the shape) including or excluding the boundary, requiring an understanding of how to plot these curves and correctly shade the appropriate region.

Linear Inequalities

Linear inequalities in two variables describe a half-plane bounded by a straight line. By graphing the line and determining which side of it satisfies the inequality, one can represent the solution area for the inequality. This concept is crucial in solving systems where linear constraints are present alongside other types of inequalities.

In Problems 35-42, graph each system of inequalities. $\left\{\begin{array}{l}x^2+y^2 \leq 9 \\ x+y \geq 3\end{array}\right.$
