Write an equation of the direct variation that includes the point (–10, –17).

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).

it's both, now can you answer my most recent question?
