Module 1.5, 2.6, & 2.7 Test Remediation

Front

What is the graph of the equation y = -x + 2?

Back

The graph is a straight line with a slope of -1 and a y-intercept of 2.

Front

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

Back

The number of vertices can vary; in this case, there are 4 vertices.

Front

What inequality represents the situation where Sarah can make no more than 8 purses a week?

Back

The inequality is x + y ≤ 8.

Front

What inequality is represented by the graph where x is greater than -3?

Back

The inequality is 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 graph the inequality x + y ≤ 8?

Back

Graph the line x + y = 8 and shade below the line.

Front

What does the feasible region represent in a graph of inequalities?

Back

The feasible region represents all possible solutions that satisfy the inequalities.

Front

What is the slope of the line represented by the equation y = -x + 2?

Back

The slope is -1.

Front

What does it mean if a point is in the feasible region?

Back

It means that the point satisfies all the inequalities in the system.

Front

How do you determine the number of vertices in a feasible region?

Back

By finding the intersection points of the boundary lines of the inequalities.
