How do I graph the inequality using intercepts. 3x + 2y > 12?

OpenStudy (shamil98):

First change it to slope-intercept form.

OpenStudy (anonymous):

so then it would be y>-3/2x+6

OpenStudy (shamil98):

Correct. Now, plot your y -intercept (which is 6 in this equation ) and form the line with rise/run.

OpenStudy (shamil98):

since y is greater than that. after graphing your line shade everything above the line.

OpenStudy (anonymous):

|dw:1386183883506:dw| that right?

OpenStudy (shamil98):

|dw:1386184020112:dw| no, the y -intercept is at positive 6 ,and you go up 3/ left 2 and down 3/ right 2 you also shade above the line since this is a greater than inequality.
