Module 1.5, 2.6, & 2.7 Test Remediation

Front

What is a vertex in a feasible region?

Back

A vertex is a point where two or more lines meet, representing a corner of the feasible region in a graph.

Front

How many vertices are typically found in a feasible region defined by linear inequalities?

Back

A feasible region can have 2, 3, 4, or more vertices depending on the number of inequalities.

Front

What does the inequality y > 2x - 4 represent graphically?

Back

It represents the area above the line y = 2x - 4.

Front

What does the inequality y < 2 represent graphically?

Back

It represents the area below the horizontal line y = 2.

Front

How do you graph the equation x + y = 3?

Back

To graph x + y = 3, find points where x and y intercepts are (3,0) and (0,3) and connect them.

Front

What does the inequality x > -3 represent?

Back

It represents all values of x that are greater than -3, which is the area to the right of the vertical line x = -3.

Front

What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables.

Front

How do you determine the solution set of a system of inequalities?

Back

The solution set is the region where the graphs of the inequalities overlap.

Front

What does the graph of y ≤ 2x - 1 look like?

Back

It includes the line y = 2x - 1 and the area below it.

Front

What does the graph of y > -2x + 3 represent?

Back

It represents the area above the line y = -2x + 3.
