Question 306899
<font face="Garamond" size="+2">


Step 1.  Stop typing your questions in ALL CAPS.  All caps is the electronic equivalent of shouting.  It is both rude and annoying.


Step 2.  Find the slope of the line that is defined by the set of points.  Take any two of the given points on that line and use the slope formula:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ m\ =\ \frac{y_1\ -\ y_2}{x_1\ -\ x_2} ]


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.


Step 3.  Recall that parallel lines have equal slopes.  That is to say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  L_1\ \parallel\ L_2 \ \ \Leftrightarrow\ \ m_1\ =\ m_2]


Step 4.  Use the point-slope form of the equation of a line to derive the desired equation, namely:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ -\ y_1\ =\ m(x\ -\ x_1) ]


where *[tex \Large m] is the slope value you calculated in Step 2 and *[tex \Large \left(x_1,y_1\right)] are the coordinates of the point through which the desired line must pass.
