(1) calculate the slope of the given line = (y2-y2) / (x2-x1)
(2) the slope from (1) = slope of parallel line
(3) use the slope from (1) and your given point and this equation to determine line....
y - y1 = m (x-x1)
where (x1,y1) is your point and m = slope from (1)

As a geometrical construction using only a compass and a straightedge, let A be the point not on line L. Choose 2 points B, C on line L. Using the compass, draw an arc of radius BC centered at point A, and another arc of radius AB centered at point C, so that the arcs intersect at new point D. Draw line through AD, which will be parallel to line L. This method uses the parallelogram ABCD as means of drawing a line parallel to a given line but through a given point not on it.
