Please note that you cannot write "the" equation of any line. You can only write "an" equation of a line. In the first place, you could just substitute the values in the point-slope form and have an equation of the desired line, or you could solve for  to put it into slope-intercept form, or you could rearrange it into standard form, namely  . Furthermore, for a given  ,  , and  ,  where  describes a set of equations with an infinite number of elements, each of which graphs to the same line in  .
First determine the slope of the graph represented by the given equation. This equation is in slope-intercept form, so the slope is equal to the coefficient on  .
Next, determine the slope of the desired line using:
Use the point-slope form of an equation representing a straight line graph.
 )
where ) are the coordinates of the given point and  is the determined slope.
