The slope is___ The y-intercept is (__).

1 answer

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

  1. Start with the given equation: \[ 9 + \frac{27}{2}x = -\frac{3}{2}y \]

  2. Isolate \( y \) on one side. First, move the term involving \( x \) to the other side: \[ -\frac{3}{2}y = -\frac{27}{2}x - 9 \]

  3. Now, multiply everything by \(-\frac{2}{3}\) to solve for \( y \): \[ y = \frac{27}{3}x + 6 \]

  4. Simplify: \[ y = 9x + 6 \]

Now we can identify the slope and y-intercept from the equation:

  • The slope \( m \) is 9.
  • The y-intercept \( b \) is 6, which corresponds to the point \( (0, 6) \).

Therefore, the answers are:

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