I believe C. Because it provides a more meaningful explanation
The first graph is what i would think
Y=3.6x is direct variation. The constant is 3.6
8y=2x is the same as y=0.25x. It is direct variation, and the constant is 0.25
1. Assuming "dinners made" is on the y-axis, DV is y=2x. The constant is 2
2. This is not direct variation, and therefore does not have a constant of variation
Hmmm idk if you want fractions but, 65/24 or 2 17/24 I think
