The Basics: System of Equations

Why are inequality graphs shaded?

• To make them look pretty
• To show which values work for the inequality
• To highlight the values that DON'T work
• To make math harder

For ≤ and ≥, what kind of line is used when graphing on a number line?

• Dashed
• Solid

For < and >, what kind of line is used when graphing on a number line?

• Dashed
• Solid

How do you say "Y < " 

• Y is less than
• Y is greater than
• Y is less than or equal to
• Y is greater than or equal to

Solid or dashed line?  Y ≥

• Solid
• Dashed

Solid or dashed line?  Y <

• Solid
• Dashed

Shade above or below? y <

• Above
• Below

Shade above or below? y ≥

• Above
• Below

Describe the line: y ≤ 2x + 5

• Solid line with a shadow below
• Solid line with a shadow above
• Dashed line with a shadow below
• Dashed line with a shadow above

In the equation y = 3x, state the y-intercept and the slope.

• y - intercept is 3 and the slope is 0

• y - intercept is 3 and the slope is 3

• y - intercept is 0 and the slope is -3

• y - intercept is 0 and the slope is 3
