The statement which correctly describes the shaded region for the inequality is ![\fbox{\begin\\\ Above the dashed line\\\end{minispace}}](https://tex.z-dn.net/?f=%5Cfbox%7B%5Cbegin%5C%5C%5C%20Above%20the%20dashed%20line%5C%5C%5Cend%7Bminispace%7D%7D)
Further explanation:
In the question it is given that the inequality is
.
The equation corresponding to the inequality
is
.
The equation
represents a line and the inequality
represents the region which lies either above or below the line
.
Transform the equation
in its slope intercept form as
, where
represents the slope of the line and
represents the
-intercept.
-intercept is the point at which the line intersects the
-axis.
In order to convert the equation
in its slope intercept form add
to equation
.
![6y-3x+3x=9+3x](https://tex.z-dn.net/?f=6y-3x%2B3x%3D9%2B3x)
![6y=9+3x](https://tex.z-dn.net/?f=6y%3D9%2B3x)
Now, divide the above equation by
.
![\fbox{\begin\\\math{y=\dfrac{x}{2}+\dfrac{1}{2}}\\\end{minispace}}](https://tex.z-dn.net/?f=%5Cfbox%7B%5Cbegin%5C%5C%5Cmath%7By%3D%5Cdfrac%7Bx%7D%7B2%7D%2B%5Cdfrac%7B1%7D%7B2%7D%7D%5C%5C%5Cend%7Bminispace%7D%7D)
Compare the above final equation with the general form of the slope intercept form
.
It is observed that the value of
is
and the value of
is
.
This implies that the
-intercept of the line is
so, it can be said that the line passes through the point
.
To draw a line we require at least two points through which the line passes so, in order to obtain the other point substitute
for
in
.
![0=9+3x](https://tex.z-dn.net/?f=0%3D9%2B3x)
![3x=-9](https://tex.z-dn.net/?f=3x%3D-9)
This implies that the line passes through the point
.
Now plot the points
and
in the Cartesian plane and join the points to obtain the graph of the line
.
Figure
shows the graph of the equation
.
Now to obtain the region of the inequality
consider any point which lies below the line
.
Consider
to check if it satisfies the inequality
.
Substitute
and
in
.
![0>9](https://tex.z-dn.net/?f=0%3E9)
The above result obtain is not true as
is not greater than
so, the point
does not satisfies the inequality
.
Now consider
to check if it satisfies the inequality
.
Substitute
and
in the inequality
.
The result obtain is true as
is greater than
so, the point
satisfies the inequality
.
The point
lies above the line so, the region for the inequality
is the region above the line
.
The region the for the inequality
does not include the points on the line
because in the given inequality the inequality sign used is
.
Figure
shows the region for the inequality
.
Therefore, the statement which correctly describes the shaded region for the inequality is ![\fbox{\begin\\\ Above the dashed line\\\end{minispace}}](https://tex.z-dn.net/?f=%5Cfbox%7B%5Cbegin%5C%5C%5C%20Above%20the%20dashed%20line%5C%5C%5Cend%7Bminispace%7D%7D)
