To find the slope and y-intercept of the equation \( 9 + \frac{27}{2}x = -\frac{3}{2}y \), we first need to rearrange it into the slope-intercept form, which is \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

Starting with:

\[ 9 + \frac{27}{2}x = -\frac{3}{2}y \]

we can isolate \( y \) by first moving everything else to the other side:

\[ -\frac{3}{2}y = -\left(9 + \frac{27}{2}x\right) \]

Now distribute the negative sign:

\[ -\frac{3}{2}y = -9 - \frac{27}{2}x \]

Next, we can multiply both sides by -1 to make \( y \) positive:

\[ \frac{3}{2}y = 9 + \frac{27}{2}x \]

Now, divide both sides by \(\frac{3}{2}\) or multiply by the reciprocal \(\frac{2}{3}\):

\[ y = \frac{2}{3} \cdot 9 + \frac{2}{3} \cdot \frac{27}{2}x \]

Calculating each term separately:

\[ y = 6 + 9x \]

Now, we rewrite it in the standard form of \( y = mx + b \):

\[ y = 9x + 6 \]

From this, we can see that:

  • The slope \( m \) is \( 9 \).
  • The y-intercept \( b \) is \( 6 \).

The y-intercept as an ordered pair is:

\[ (0, 6) \]

In summary:

  • The slope is \( 9 \)
  • The y-intercept is \( (0, 6) \)

I apologize for any mistakes in my previous response. Let's carefully go through the problem step by step to find the correct slope and y-intercept for the equation \( 9 + \frac{27}{2}x = -\frac{3}{2}y \).

Step 1: Rearranging the Equation

We start with the equation:

\[ 9 + \frac{27}{2}x = -\frac{3}{2}y \]

We want to solve for \( y \). First, isolate the term involving \( y \):

\[ -\frac{3}{2}y = -\left(9 + \frac{27}{2}x\right) \]

This simplifies to:

\[ -\frac{3}{2}y = -9 - \frac{27}{2}x \]

Now, multiplying through by -1 gives us:

\[ \frac{3}{2}y = 9 + \frac{27}{2}x \]

Step 2: Isolating \( y \)

Next, we need to solve for \( y \) by multiplying both sides by \( \frac{2}{3} \):

\[ y = \frac{2}{3}(9 + \frac{27}{2}x) \]

Distributing \( \frac{2}{3} \) gives:

\[ y = \frac{2}{3} \cdot 9 + \frac{2}{3} \cdot \frac{27}{2}x \]

Calculating each term:

  1. \( \frac{2}{3} \cdot 9 = 6 \)
  2. \( \frac{2}{3} \cdot \frac{27}{2} = 9 \)

Putting it all together:

\[ y = 9x + 6 \]

Step 3: Identifying the Slope and Y-Intercept

From the equation \( y = 9x + 6 \):

  • The slope \( m \) is \( 9 \).
  • The y-intercept \( b \) is \( 6 \).

Final Answer

The slope is \( 9 \) and the y-intercept is:

\[ (0, 6) \]
