Quiz on Solving Systems of Linear Equations and Inequalities

What is the first step in solving a system of linear equations by graphing?

• Calculate the slope of each line.

• Shade the region above the lines.

• Graph both lines on the same coordinate plane.

• Find the intersection of the lines.

When graphing a system of linear inequalities, what does a dashed line represent?

• An equation with no solution.

• An equation with a 'greater than' or 'less than' sign.

• An equation with a 'less than or equal to' sign.

• An equation with a 'greater than or equal to' sign.

How can you verify that you have shaded the correct region for a system of inequalities?

• By testing a point in the shaded region.

• By ensuring the lines are parallel.

• By calculating the slope of the lines.

• By checking if the lines intersect.

What shape does the graph of an absolute value equation typically form?

• A V-shape

• A straight line

• A circle

• A parabola

What must you remember to do when dividing an inequality by a negative number?

• Subtract the same number from both sides.

• Multiply both sides by two.

• Switch the inequality sign.

• Add the same number to both sides.

What is the result when two lines in a system are parallel?

• The lines intersect at one point.

• There is one solution.

• There are infinite solutions.

• There is no solution.

In the context of graphing inequalities, what does it mean if the shaded regions do not overlap?

• There is no solution.

• There is one solution.

• There are infinite solutions.

• The solution is undefined.
