good now, y=(whatever line) is a set of all points on that line \(y\ge(some~~line)\) means "y is greater than or equal to that line" so that would be all the points above the line and including the line that is represented by a whole line (to show that the y= part is included) and shading above (because of the y>... part)

6 years ago
OpenStudy (turingtest):

\[y>(some~~line)\]means the set of all points above, but \(not\) including the line itself that is represented by a dotted line (to show the absence of the y= part) and shading above (to show the y> part)

6 years ago
OpenStudy (anonymous):

lol jc

OpenStudy (turingtest):

the same argument applies for \(y\le(whatever)\) and \(y<(whatever)\) only the shading would be below the line instead.

6 years ago
OpenStudy (turingtest):

based on all that, which is your answer?

6 years ago
OpenStudy (turingtest):

"dotted"="dashed"

6 years ago
OpenStudy (anonymous):

dashed does not included the origin

6 years ago
OpenStudy (turingtest):

and why do you think the origin is not included? for the origin to be included, the point y=0, x=0 must satisfy the inequality does it?

6 years ago
OpenStudy (turingtest):

you are correct, I'm just pressing you for a deeper understanding

6 years ago
OpenStudy (turingtest):

plug in y=0, x=0 and what do you get? y>-4x+6 0>-4(0)+6 0>6 which is not true, hence the point (0,0) (also known as the origin) is not a solution good job :)
