Linear Function Characteristics

• the independent variable is distance
• the independent variable is d=25 t
• the dependent variable is time
• the dependent variable is distance

The graph shows the cost of mailing a package based on its weight.  Which statement is true about the situation?

• The dependent variable is total cost

• The dependent variable is weight

• The independent variable is total cost

• The independent variable is cost of a package

Derrick started a new job at McDonald's. He makes $10 per hour. Which graph models his total weekly earnings in terms of the number of hours he works?

• 
• 
• 
• 

The table shown is:
(hint: find the rate of change)

• proportional function.

• linear function.

• non linear function.

• Not a function.

The graph shown is:

• linear function but not proportional.

• function, but not linear or proportional.

• proportional function.

• Not a function, linear or proportional.

The mapping shown is:

• Not a function, because there are letters.

• Not a function, because two different numbers go to C.

• A function, because none of the x values go to more than one y value.

• A function, because the numbers are in order.

The table shown is:

• Proportional because it goes through the origin.

• Linear, because there is a pattern.

• A function, because all of the x values are different.

• All of the above.

The table shown is:

• Proportional, because it is going up by 2 each time.

• Linear, because it is going up by two each time.

• Not a function, because 1 appears in the table twice.

• A function but non linear, because it doesn't start at zero.

Which of the following sets of ordered pairs represents a proportional relationship?

• <(0, 5)(1, 10)(2, 15) (3, 20)>

• <(3, 15)(5, 25)(8, 40) (12, 60)>

• <(4, 6)(8, 6)(2, 6)(5, 6)>

• <(3, 6)(4, 8)(5, 10) (3, 12)>

Which of the tables shows a proportional relationship?

• A and B only

• B and C only

• A, B and C

• none of them
