You need to start with the two point form because you are given two points:
:

:
Plug in the values:

:
And simplify:

Giving you the point-slope form: , where m is the slope and (,) is the point. m in the example is -2, and (5,-8) is the point.
:
Simplify a little more:

and you have the slope intercept form , where m is the slope and b is the y-intercept. m in the example is -2, and b is 2.
:
Standard form is , where a and b are not both 0
:
And in this problem that would be:
(a=2, b=1, and c = 2)
:
