Direct Variation Table

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

Is this a direct variation?

If I divide y by x are all the values equal?

• Yes

• No

• I do not know.

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