An equation of direct variation is something like
If we have a value for x and y, we simply have to plug these values and see which constant k suits our case:
So, the relation
is a relation of direct variation and it includes the point (-10,-17).

Answer:
no, y does not vary directly with x
Step-by-step explanation:
If there is direct variation, the constant of variation can be found as ...
k = y/x
Here, those ratios are ...
y/x = 6/3 = 2
y/x = 18/6 = 3
y/x = 24/8 = 3
The ratio of y to x is NOT A CONSTANT, so <em>there is no direct variation.</em>
