.


The comma &amp;nbsp;&quot; , &quot; &amp;nbsp;separates the coordinates &amp;nbsp;&quot; 1&quot; &amp;nbsp;and &amp;nbsp;&quot; k &quot; &amp;nbsp;in the point notation &amp;nbsp;(-1,k).


It works as a separator or a divider in this case.



It is my answer, &amp;nbsp;&amp;nbsp;if I correctly understand your question in the post.
