3.06 Graphing Inequalities

What form of linear equation is y = mx + b

• Standard form

• Slope-intercept form

• Point-slope form

• Intercept-point form

Which way does the graph go for -x values?

• Up

• Right

• Down

• Left

A dashed line on a coordinate plane represents that...

• There are solutions on that line

• There are NOT solutions on that line

Given the equation y = 2x - 3, identify the y-intercept

What is another name for the coordinates (0, 0)?

• Origin
• Center
• Null Point
• Point A

The point (2, -2) is a solution to the inequality y > 3x -4

• True

• False

In which scenario(s) would you need to flip the inequality sign?

Select all that apply

• Adding a negative to both sides

• Subtracting a negative from both sides

• Multiplying both sides with a negative

• Dividing both sides with a negative

Let's practice:

Which of the following is a solution to the inequality:

y = -x + 5

• (1, 3)
• (3, 1)
• (0, 5)
• (2, 2)

Which inequality is represented by this graph?

• y < 1/3 x - 3

• y < 1/3 x + 3

• y > 1/3 x - 3

• y > 1/3 x + 3

Two things that are true about this graph are:

• (0, 0) is a solution

• (0, 0) is NOT a solution

• The boundary line is solid, therefore points on the line are solutions

• The boundary line is solid, therefore points on the line are NOT solutions
