The r value is r = -0.015 which is much closer to 0 than it is to -1, so this means that the linear regression line is a bad model to estimate the points. You're better off using some other model (eg: quadratic model), or it's possible that the data isn't connected at all and it's random noise.
If r were closer to -1, then we'd be more confident that the lines all fall around the same straight line that slopes downward.
