Question

the type of line used to indicate that values on the line are not included in the solution is a line.
when the inequality includes the boundary, we use a line to graph it.
the area where the shaded regions of all inequalities overlap is known as the to the system.
in a system of inequalities, the inequalities must be graphed on a plane.
the symbol in an inequality means that the boundary line is included in the solution set and that you shade below the line.
the process of checking whether a point belongs to the solution set is called a.
graphing each inequality in the system and then determining the overlapping area is known as the method.

Explanation:

1. First Question

In graphing inequalities, a dashed (or broken) line is used when the values on the line are not part of the solution set (for strict inequalities like \( < \) or \( > \)).

For inequalities that include the boundary (non - strict inequalities like \( \leq \) or \( \geq \)), a solid line is used to show that the boundary points are part of the solution.

In a system of inequalities, the region where the shaded areas of all individual inequalities overlap is the set of all solutions that satisfy every inequality in the system, which is called the solution set (or feasible region).

Answer:

dashed (or broken)
