Question 273307
<font face="Garamond" size="+2">


*[tex \LARGE m\ =\ -3] through (4, 8)


Use the point-slope form of the equation of a line to derive the desired equation:


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



where *[tex \Large \left(x_1,y_1\right)] are the coordinates of the given point and *[tex \Large m] is the slope of the given line.


So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ -\ (8)\ =\ -3\left(x\ -\ (4)\right)]


Simplification is left as an exercise for the student.
