**MathMate**, Sunday, October 25, 2009 at 4:40pmFirst, from a given line, the slope can be identified if the equation of the line is put into the slope-intercept form as:

y = mx + b

For example,

2x + 3y = 5 can be rearranged to

y = (-2/3)x + 5/3

From which we can identify the slope as (-2/3).

One the slope is defined, if the line is to pass through a given point with coordinates (x1,y1), the equation of the line sought is:

y = m(x-x1) + y1

So if a line parallel to the above line is to pass through (3,2), the equation would be:

y = (-2/3)(x - 3) + 2, or

y = (-2/3)x + 4
