WebThis is a downward-sloping line. I would say this is a negative. This is a negative linear relationship. But this one looks pretty strong. So, because the dots aren't that far from my line. This one gets a little bit further, but it's not, there's not some dots way out there. And so, most of 'em are pretty close to the line. WebDirect variation can be negative. To be more precise, the constant of variation k can be less than zero (k < 0). In practical terms, k < 0 means that y decreases as x increases.
