The equation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ce39ab6df0e7ad36b882ad94cea81402.png\")
.
Rewrite the equation ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ce39ab6df0e7ad36b882ad94cea81402.png\")
in slope - intercept form by solving for y.
Subtract x from each side.

The equation ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9757047fc3d4088f8730a71d84c83acd.png\")
is in the form ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=37a3162ea0616fe6c23aa6e01e176309.png\")
where m is the slope and b is the y - intercept of the equation of graph.
So, the slope of the line is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=85d215f649fdd96c751c3513e334482a.png\")
and the y - intercept is 4.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The option C is correct answer.
