Question 251099
<font face="Garamond" size="+2">


A relation is not a function if any single possible input value can produce more than one output.  In that the given *[tex \LARGE y]-coordinates are unequal, if the *[tex \LARGE x]-coordinates were equal, you would have one input/more than one output and you would not have a function.  So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5k\ +\ 3\ =\ 3k\ -\ 5]


and solve for *[tex \Large k]
