You can put this solution on YOUR website!
When you are given two points, use the Two-Point form of an equation for a line.
(x\ -\ x_1) )
where ) and ) are the coordinates of the given points.
When you are given a slope and a point, use the Point-Slope form:
 )
where are the coordinates of the given point and  is the given or calculated slope.
If you are given an equation representing a line and asked to find an equation of a line parallel to that line through a given point, use:
and then use the Point-Slope form.
If you are given an equation representing a line and asked to find an equation of a line perpendicular to that line through a given point, use:
and then use the Point-Slope form.
If you are asked to put your answer in standard form, rearrange the equation to look like:
Some teachers/professors/instructors/textbook authors require that A, B, and C be integers, and some also require A to be a non-negative integer.
If you are asked to put your answer in Slope-Intercept form, rearrange the equation to look like:
where is the slope of the line and  is the  -coordinate of the -intercept.
