where m is the slope and b is the y-intercept.
\The slope of the line is ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=51e38f1669790d73bbd16877b706bce2.png\")

= -3.
The line crosses the y-axis at (0, 4). So the y-intercept is 4.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
Substitute m = -3 and b = 4 in slope-intercept form equation.
