You're correct to say that plotting -2/+5 and 2/-5 will both yield the same slope. This is because -2/+5 = 2/-5 = -(2/5)
And yes, if we have a negative slope, the negative sign should be applied to EITHER the rise or the run.
Likewise, if we have a positive slope, like 3/7, plotting +3/+7 or -3/-7 will yield the same slope. This is because +3/+7 = -3/-7 = 3/7
