Please help! gradients...?

These are what i've plotted on a graph:

(.343, .242)
(.643, .438)
(.259, .174)

What is the gradient?

if these points are on a line
slope=(.242-.174)/(.343-.259)
=.068/.084
=68/84
=17/21=slope

(.242 - .174)/(343 - 259) = 0.80952
(438 - 242)/(643 - 343) = 0.65333
(438 - 174)(/(643 - 259) = 0.6875
so
y = - 0.071800764 1.054384921x - 0.406746032x^2
y' = 1.054384921 - 0.813492064x
