Answer 1

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

Starting with the equation:

\[
9 + x = -y
\]

We can rearrange it to isolate \(y\):

\[
-y = x + 9
\]

Now, multiply both sides by \(-1\):

\[
y = -x - 9
\]

From this equation, we can identify:

- The slope (m) is \(-1\).
- The y-intercept (b) is \(-9\).

The y-intercept in ordered pair form is \((0, -9)\).

Thus, the slope is \(-1\) and the y-intercept is \((0, -9)\).
