Mathematical relationships, science, and vocabulary How are things related? Mathematical relationships, science, and vocabulary

Mathematical relationship words: Linear Non-linear Proportional Exponential Quadratic Inversely proportional These three are good enough for now.

If two things are proportional… Increasing one will… Doubling one will... If one is zero… increase the other. double the other. then the other is zero.

Which one of these is a picture of direct proportion?

Graph A: If you double the x-value, does the y-value double? Any other reason why these are not proportional?

Graph B: If you double the x-value, does the y-value double? Any other reason why these are not proportional?

Graph C: If you increase the x-value does the y-value increase? If you double the x-value, does the y-value double? If the x-value is zero, is the y-value zero?

Linear (but not proportional):

Non-Linear:

A picture of direct proportion:
