Difference from "slope"

What exactly distinguishes direction from "slope"? From the definition at slope it appears that that term is meant independent of displacement, so conceivably "direction" could be meant to be dependent. But nothing in this article supports such an answer. To the contrary, the text here relies on the same displacement-independent terms "orthogonal", "diagonal" and "oblique". So, are the two just used synonymously? If so, what's the correct term to distinguish (1,2) from (4096,8192)? Micromegas (talk) 09:21, 12 March 2018 (UTC)

"Direction" is just one of "orthogonal", "diagonal" and "oblique", with the last one being a catch-all term for anything that's neither orthogonal nor diagonal. "Slope" further distinguishes different oblique directions. The difference between (1,2) and (4096,8192) is displacement; the direction is the same (oblique), as is the slope (2).
