Algebraic Representations

Which equation matches the table? 

• y = x + 4

• y = 5x

• y = x - 4

• y = x + 16

Which graph matches the table?

• A

• B

• C

• D

Which equation matches the graph?

• y = 60x

• y = 40x

• y = 80x

• y = 20x

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. 

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.

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

ILTexas Middle School is organizing a walk-a-thon to raise money to go on a field trip.  Students are asking people to pledge $0.10 per lap during the walk-a-thon. Which equation can be used to describe the table above?

• L = 0.10m

• m = 0.10L

• m = 0.10 + L

• L = 0.10 + m
