Multiple Representations given an equation

Identify the m and b in the following equation:
y = 2x + 5

• m = 5
  b = 2
• m = 2
  b = 5
• m = y
  b = x
• why are there letters in math?!

What is the rate of change (m) for the table?

• m = 90
• m = 18
• m = 1/9
• m = 9

Does this table represent a proportional or non-proportional relationship?  Why?

• It is proportional because 5x + 1 = y
• It is not proportional because it has a constant value in the equation. 

Is this a proportional equation?  Why?

• It is not proportional because it doesn't have a constant.
• It is not proportional because it doesn't have a constant rate of change.
• It is proportional because if x = 0, y = 0.
• It is proportional because it has a y intercept.
