• y = 4 + 5x

• y = 5 + 4x

• y = 4•5•x

• y = 5x - 4

Is the following equation proportional or non proportional:
y= 4x

• Proportional

• Non Proportional

• Proportional

• Non Proportional

You plan to go snowboarding. The resort charges $15 an hour in addition to $25 to rent a board. Write an equation that represents the cost to go snowboarding for the day.

• y=15x-25

• 15x+25y=100

• 25x+y=15

• y=15x+25

Is the following equation proportional or non proportional:
y= 4x - 5

• Proportional

• Non Proportional

y= 5 + 3x

• Proportional

• Non Proportional

What can you use to represent linear relationships?

• verbal descriptions

• equations

• graphs

• tables

• all of the above

Which equation matches the graph?

• y = 1/3x + 3

• y = 3x

• y = x +3

• y = 3x + 3

Which equation matches the table?

• y =4 x + 7

• y = 1/4x +11

• y = 4x -11

• y = 11x + 4

Does this graph show a proportional relationship?

• Yes, because it is linear

• Yes, because it is linear and goes through the origin.

• No, because it is not linear

• No, because it does not go through the origin.
