Question 237292
<font face="Garamond" size="+2">


Use the point-slope form of the equation of a straight line:


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


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


The question "Which equation is correct...?" doesn't have an answer.  The results of performing the appropriate substitutions above is <b><i>an</i></b> equation which solution set is a set of ordered pairs that when graphed is a straight line with the given slope and containing the given point.  However, that is just one of an infinite number equivalent representations of the same thing.  Had you asked, "Which of the following equations is a correct representation...?" and then followed it with a list of two-variable linear equations one of which is equivalent to the results of the application of the form above, <b><i>then</i></b> the question has an answer.
