Exploring Systems of Inequalities

What must you do to the inequality sign when you multiply or divide by a negative number?

• Leave it unchanged

• Flip it

• Add a line under it

• Remove the line under it

What is the first step in solving an inequality?

• Check if Y is alone

• Identify the slope

• Draw the arrows

• Identify the Y intercept

Which symbol represents 'greater than'?

• <

• >

• ≤

• ≥

When should you use a dashed line in graphing inequalities?

• When the inequality is greater than or equal to

• When the inequality is less than or equal to

• When the inequality symbol does not have a line under it

• When the inequality symbol has a line under it

In the example problem, what is the slope of the first inequality?

• 1 over -2

• -2 over 1

• 1 over 4

• 4 over 1

For the first example problem, where should you color the graph?

• Above the line

• Below the line

• To the left of the line

• On the line

In the homework example, what is the Y intercept of the first inequality?

• 3

• -2

• 5

• -3

What is the slope of the second inequality in the homework example?

• 1 over 6

• -1 over 6

• 6 over 1

• -6 over 1

What tool can you use to graph inequalities if you don't understand how to do it by hand?

• Calculator

• Spreadsheet

• Graph paper

• Desmos

In Desmos, what should you do after copying the inequalities?

• Draw the arrows

• Change the settings

• Identify the Y intercept

• Copy the intersection
