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=a957401b9c362e94179839a0028f04a3.png\")
The line crosses the y-axis at (0, – 4). So y-intercept is – 4.

Substitute m = 1 and b = – 4 in slope-intercept form line equation.
