Use the two-point form of an equation of a line:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ -\ y_1\ =\ \left(\frac{y_1\ -\ y_2}{x_1\ -\ x_2}\right)(x\ -\ x_1) ]



where *[tex \Large \left(x_1,y_1\right)] and *[tex \Large \left(x_2,y_2\right)] are the coordinates of the given points.


However, be aware that you cannot write &lt;b&gt;&lt;i&gt;the&lt;/i&gt;&lt;/b&gt; equation of a line.  Since there are infinite representations of any given line, the best you can do is write &lt;b&gt;&lt;i&gt;an&lt;/i&gt;&lt;/b&gt; equation of a line.
