Presentation transcript:

Equations Inequalities Tables/Graphs Review I can solve and graph equations using properties of equations. I can solve and graph inequalities using properties of inequality. I can identify independent and dependent quantities from tables and graphs.

Which property fits this problem?

Clue words can help you identify which operation to use to write an equation.

Look for clue words! Try to write your own equation for each answer choice.

What is the difference between an expression and an equation??

In a graph, the independent variable is usually show on the horizontal(x) axis and the dependent variable is on the vertical (y) axis. Which is your independent variable? Which is your dependent variable?

You can use inequality symbols with variables to describe quantities that can have many values.

Graphing Inequalities

Using Properties of Inequalities to Solve

What is your first step to solving this inequality?

Which answer choice fits the criteria from the problem?

Pay attention to which side of the inequality sign the t is on!

What should you do with your ordered pair first?

What comes first? x or y?

Practice!

Graphing Equations Graph the equation by completing a process table.

Complete the process table. What values for x should you use?

Make a process table first!

Writing Equations from Tables Look for the pattern. How do you get from x to y??
