The slope-intercept form line equation is ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=76e64b5521ed7c4158682063595d6643.png\")
, where m is slope
and b is the y-intercept.
\The slope of the line is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ab9e7b3ff9c06aaa3b00c631cceaaebe.png\")
The line crosses the y-axis at (0, 0). So y-intercept is 0.
