hi. I think i can help you.
OpenStudy (anonymous):
the type of line is either solid or shaded. This is entirely related to whether or not the inequality contains an equal sign.
OpenStudy (anonymous):
solid or dashed*
OpenStudy (anonymous):
yes... nice
OpenStudy (anonymous):
so does the line slant from bottom right to upper left or from bottom left to upper right?

if you add 3x to both sides, you will get y>3x+6
OpenStudy (anonymous):
so this is the equation of the boundary line. well, y=3x+6 is the equation of the boundary line. however, because there is no equal sign in the inequality, the line is dashed.
OpenStudy (anonymous):
notice how i put the inequality in slope intercept form
OpenStudy (anonymous):
y>mx+b
OpenStudy (anonymous):
where m=3 and b=6

so far so good or are you feeling queasy with questions?
OpenStudy (anonymous):
i didnt see you question about the origin, but it too can be answered shortly. The origin is the point (0,0). Does the shaded region contain the point (0,0)?
OpenStudy (anonymous):
pinkmommy, still there?
OpenStudy (anonymous):
well i guess you are not still there.. ummm... the region does not contain the origin. i hope this helps. take care
OpenStudy (anonymous):
