1. How do you use an equation to show the relationship between two variables? j = 10s

2. In this lesson you will learn how to show the relationship between independent and dependent variables by writing an equation.

3. Let’s Review An equation is a mathematical sentence with an equal sign.

4. Core Lesson Carlie is selling jars of strawberry jam to raise money for her soccer team. How much money will she make? the amount of money earned the number of jars of jam = m = s

5. Core Lesson 5j = m coefficient 5 $$ (1)(1) 5 = $5 (2)(2)5= $10 Which variable is independent? Which is dependent? independent variable dependent variable

6. Core Lesson j (number of jars) m (amount of money) 1$5.00 2 $10.00 4 3 5 $15.00 $20.00 $25.00 50 45 40 35 30 25 20 15 10 5 0 9 8 76543210 amount of money jars of strawberry jam Jars of Strawberry Jam (3)(3) 5 = $15 (5)(5) 5 = $25

7. A Common Misunderstanding 10 dependent variable 2310 The amount of money earned influences the number of jars? independent variable Independent Variable: Dependent Variable: is the variable that is changing. is the variable that is affected by the change. 5 $$

8. In this lesson you have learned how to show the relationship between independent and dependent variables by writing an equation.
