I just did this one for you, but here it is again in case you missed it.
You can't do exactly what you ask. You asked for the equation for a line, but since there are an infinite number of equivalent representations of any given line in equation form, the best you can do is write an equation of the line that fits the given criteria. Equation is spelled with a "t" not an "s"
Use the slope formula to calculate the slope of the line that contains )
and )
.
where )
and )
are the coordinates of the given points.
Since
Which is to say parallel lines have identical slopes, by calculating the slope of the line through and , you now know the slope of the desired line.
Use the point-slope form of an equation of a line:
 )
where are the coordinates of the given point )
and 
is the calculated slope.

My calculator said it, I believe it, that settles it
