Algebraic Representations of Two-Variable Relationships

The table shows the relationship between x and y, where y is the dependent variable. 

Write an equation to represent the relationship in the table.

Type the equation without spaces and lower case.

The tables show the relationships between x and y for two data sets.

• Both data sets show additive relationships.  In Data Set I, y is 5 more than x, and in Data Set II, y is 6 more than x.

• Both data sets show multiplicative relationships.  In Data Set I, y is 3 times x, and in Data Set II, y is 5 times x.

• Data Set I shows an additive relationship in which y is 5 more than x.  Data Set II shows a multiplicative relationship in which y is 5 times x.

• Data Set I shows a multiplicative relationship in which y is 6 times x.  Data Set II shows an additive relationship in which y is 4 more than x. 

Janice bought 5 basketball game tickets for a total of $60.  Each ticket cost the same amount. 

Complete the table by selecting the correct list of missing numbers to show the relationship between the number of books bought and the total cost in dollars.

• x= 2, 4, 5

  y= 12, 36, 60

• y= 2, 4, 5

  x= 12, 36, 60

Two equations are shown below. Which of the statements best explains the relationship between the equations?

• In y = x + 3, the value of y is 3 more than the value of y = 3x.

• In y = 3x, the value of y is 3 times the value of y in the equation y = x + 3.
