The slope-intercept form line equation is ![\"\"](\"../../../../MathKey/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 ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=576614710793d893592350fc0de72c7c.png\")
The line crosses the y-axis at (0, 4). So y-intercept is 4.
