Question 199388
<font face="Garamond" size="+2">


Use the two-point form of the 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.


Substitute and simplify.


You cannot derive "the" equation of the line.  There are an infinite number of ways to represent the equation of any line.  All you can do is provide "an" equation whose graph is a line that satisfies the given conditions.
