Question

For questions 1-3

Answer 1

Number 2 is D. The pattern is quite simple, basically the formula for direct variation is y=kx, so in number 2 the problem shows -12x=6y, so then you would end up dividing the numbers, and this should you solve your other answers.
Hope this helps!

Answer 2

1. A - Not a Direct Variation

2. D - Direct Variation, Constant of Variation is -2

3. B - Direct Variation, Constant of Variation is 1/2

4. A - y = -5x

5. C - y = 5/2x

6. D - y = 2.6x
