Solving Systems of Inequalities by Graphing

What is the slope of the first boundary line in the initial example?

• -1

• 2

• -2

• 1

Why is the first boundary line dotted?

• Because it represents a less than inequality

• Because it represents an equal to inequality

• Because it represents a less than or equal to inequality

• Because it represents a greater than inequality without an equal to sign

What point is used to test the shading region for the first inequality?

• (2,2)

• (0,0)

• (0,4)

• (1,1)

What is the y-intercept of the second boundary line in the initial example?

• (0,-4)

• (0,4)

• (0,2)

• (0,-2)

Where do the shaded regions of the first and second inequalities overlap?

• Top left region

• Bottom left region

• Bottom right region

• Top right region

What is the slope of the boundary line in the new set of inequalities?

• 1/2

• 1

• 2

• -1

How is the absolute value inequality rewritten?

• As a quadratic equation

• As a linear equation

• As two separate inequalities

• As a single inequality

What is the y-intercept of the horizontal line y = 3?

• (3,0)

• (0,3)

• (0,-3)

• (3,3)

What is the shading region for the inequality y < 3?

• Above the line

• Below the line

• On the line

• To the left of the line

What is the solution to the final example where the shaded regions do not overlap?

• Infinite solutions

• Two solutions

• No solution

• One solution
