1/2
3/4
1
2

Answer 1

For direct variation use y = mx (this implies y varies directly as x) where m is the constant of variation.

Answer 2

Now all you have to do is substitute the given coordinates for x and y respectively and solve for m (the constant of variation).

Answer 3

is it B?

Answer 4

Yes!
