If I have a table of values like this one, without graphing how could I tell if it's a direct variation or not?

• Divide y by x. If all the values are the same number it is proportional (direct variation)

• If both x and y have some sort of a pattern then it's a direct variation

When we have real-world problems with graphs and tables we often talk about INDEPENDENT and DEPENDENT variables.

Independent variables just are... we have no control over them. What's an example of an independent variable?

• Time

• Money earned

• Number of hot dogs eaten

• Height a plant grew

When we have real-world problems with graphs and tables we often talk about INDEPENDENT and DEPENDENT variables.
Which value, x or y, are usually the independent variable?

• x

• y
