To find the slope and the y-intercept of the equation \( 9 + \frac{27}{2}x = -\frac{3}{2}y \), we need to rearrange the equation into the slope-intercept form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.
Starting with the original equation:
\[
9 + \frac{27}{2}x = -\frac{3}{2}y
\]
First, we can isolate \( y \) by multiplying the entire equation by \(-\frac{2}{3}\) to eliminate the coefficient of \( y \):
\[
-\frac{2}{3}(9 + \frac{27}{2}x) = y
\]
Now let's simplify the left side:
\[
y = -\frac{2}{3} \cdot 9 - \frac{2}{3} \cdot \frac{27}{2}x
\]
Calculating each term:
\[
y = -6 - 9x
\]
This can be rewritten in the standard \( y = mx + b \) form:
\[
y = -9x - 6
\]
From this equation, we can identify the slope \( m \) and the y-intercept \( b \):
- The slope \( m \) is \(-9\).
- The y-intercept \( b \) is \(-6\).
Finally, we express the y-intercept as an ordered pair. The y-intercept occurs at \( x = 0 \):
\[
(0, -6)
\]
Therefore, the slope is \(-9\) and the y-intercept is \((0, -6)\).
**Final answer:**
The slope is \(-9\). The y-intercept is \((0, -6)\).
