I say "ok" to my parents when they ask a question as a joke, but that has happened to me and it's just annoying. If you don't find it funny then don't laugh at all and don't say anything-
When someone replies "ok" and I'm trying to like make them laugh lol- it just gives me the "dead" and "dreadful" vibe. Like- it didn't make them laugh or something....or maybe my joke wasn't funny. Or even- it just like makes me think- "wait- did they just like not understand my joke?" Which gives me the "wait-" vibe.
Start on the y-axis and put a point at 490 bc it the y-intercept and then from there go up 2 and right 3 and put a point there and keep going and to go down you just go down 2 and left 3 and the point it.
