Which statement about the points (5, 7) and (10, 12) is true?

There is not enough information to determine if the points show direct variation.

They show direct variation because y = x + 2 and 10 – 5 = 12 – 7.

The line they are on does not show direct variation.

They show direct variation because the line they are on has a positive slope.
