The slope of the line can be find as
[tex]m = \frac{y1-y2}{x1-x2}[/tex]
Lets consider first point (x1,y1) as (3,2)
and second point (x2,y2) as (-2,-2)
now by putting the values in the slope equation
[tex]m = \frac{2--2}{3--2}[/tex]
[tex]m = \frac{4}{5}[/tex]
[tex]m = 0.8[/tex]
the slope of the line that passes through the points (3,2) and (-2,-2) is 0.8.
