Point deform controlling a slope

i am a beginner with grasshopper, so it might sound stupid:
I want to control some of a curve control points in the Z direction, and i would like to be able to control the difference between each point, and in this way to control the curve slope.
does anybody got an idea?

To be more clear,
i’m looking for a way to control the slope, as shows the arrows in he image


The .gh you uploaded doesn’t have your curve internalized

try this:
move control points_help.gh (15.1 KB)

for some reason I can’t edit my previous response - anyway forgot to return curve:

move control points_help_2.gh (15.1 KB)

yeah, it works.
Thank you very much _corellaman
