Equations, Tables, and Graphs Review

Which equation best represents the relationship between x and y shown on the table?

• y = x + 1

• y = x × 5

• y = 4x + 1

• y = 5x + 1

Which ordered pair does NOT represent the equation y = x + 3?

• (1, 4)

• (3, 9)

• (12, 15)

• (18, 21)

What is a dependent variable?

• A variable whose value is already given.

• An ordered pair you must graph.

• A variable whose value is found by substituting the independent variable into the rule and solving.

• All variables.

What is the rule?

• The equation used to find the dependent variable.

• The x value given in the table.

• The pair of numbers used to graph.

• The y value found when solving the equation.

What is the independent variable?
