Answer 29

Exactly right Ashely.

Answer 30

yay

Answer 31

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)

Answer 32

\[y>(some~~line)\]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)

Answer 34

lol jc

Answer 35

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

Answer 36

based on all that, which is your answer?

Answer 37

"dotted"="dashed"

Answer 38

dashed does not included the origin

Answer 39

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?

Answer 40

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

Answer 41

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 :)
