Your two points are (-1, 3.2)

and

The slope

is the difference in

over the difference in

So we have
$m=\frac{(-8.6)-(3.2)}{(2.6)-(-1)}$
⇒ $m=\frac{-8.6-3.2}{2.6+1}$
⇒ $m=\frac{-11.8}{3.6}$

As a fraction, this is $-\frac{59}{18}$

As a decimal, this is about -3.27777...

For the y-intercept, you use
y=mx+b

Plug in the coordinates of one of the points and also the slope
We'll use (-1, 3.2)

⇒

⇒

which I believe comes out to $-\frac{7}{90}$
