Question

Which of the following statements are true about the function y = x + 2?

The function is a direct variation.
The function does not go through the origin.
The constant of variation is 2.
Y is 4, when x is 2.

Answer 1

1 is false, because a direct variation is of the form y = mx, with no vertical shift

Answer 2

2 is true because if you plug in:
\[(0) = (0) + 2\]
you get a false statement, so the origin isn't a point on the line.

Answer 3

wat about 3 and 4

Answer 4

2 and 4 is true

Answer 5

yes

Answer 6

2 and 4 are the only true statements

Answer 7

the constant of variation is 1

Answer 8

or

Answer 9

actually there may not even be one

Answer 10

look, the answer is 2 and 4

Answer 11

four is easily checked by substituting the values of the variables into the equation.

Answer 12

\[(4) = (2) + 2\]
