Question 184635
<font face="Times New Roman" size="+2">


You need to use the Two-Point form of the equation of a straight line because you are given two ordered pairs to define your line.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  y - y_1 = \frac{y_2 - y_1}{x_2 - x_1}(x - x_1)]


Where *[tex \Large P_1:(x_1,y_1)] and *[tex \Large P_2:(x_2,y_2)] are your given points.


It really doesn't matter which point you select as #1 and #2, so I just selected:  *[tex \Large P_1:(2,1)] and *[tex \Large P_2:(4,-2)] giving us:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  y - 1 = \frac{-2 - 1}{4 - 2}(x - 2)]


Now all you have to do is the arithmetic and algebraic manipulation to put the equation into the requested form, namely:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  Ax + By = 8]

*[tex \LARGE e^{i\pi} + 1 = 0]
