you just find the coordinate point. then, use your slope 2/3 (up 2, right 3) :)
EX: if your slope was negative, you’d do the same thing, but opposite -2/-3 (down 2, left 3)
hopefully this helps, good luck with math!! <3
(ps sorry if the drawing bothers you, but I wanted to show you as best as I could on how to solve your question :) )
