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!

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

On your own paper graph each system of equations and then describe it: y=x+4 3x+5y=10

Each equation form a straight slanting line. For the first equation, it is slanting towards the right which denotes that it has a positive slope. For the the second equation, its plot is slanting towards the left denoting that its slope is negative. Common to both equation is the point (-1.25, 2.75). At this point, the two lines intersect.

Lines k and p are perpendicular, neither is vertical and p passes through the origin. Which is greater? A. The product of the sl
AlladinOne [14]
What do we know about those two lines?

They are perpendicular, meaning they have the same slope.
We know the slope of both is not zero (neither is vertical).
Therefore either
1) Both slopes are positive and therefore the product is positive
2) Both slopes are negative and therefore the product is positive (minus by a minus is a plus)

For the y intercepts, we know that the line P passes through the origin.
Therefore its Y intercept is zero.
[draw it if this is not obvious and ask where does it cross the y axis]
Therefore the Y intercept of line K and line P is zero.
[anything multiplied by a zero is a zero]

So we know that the product of slopes is positive, and we know that the product of Y intercepts is zero.
So the product of slopes must be greater.
