The given equation is \( x + 8 = 0 \).

We can solve for \( x \):

\[
x = -8
\]

This represents a vertical line at \( x = -8 \), meaning that no matter what value \( y \) takes, the \( x \)-coordinate will always be \( -8 \).

For Step 2, you are asked to plot a point on this line with the y-coordinate \( y = -7 \). Since the line is vertical at \( x = -8 \), the point to plot would be \( (-8, -7) \).

Would you like more details or any clarifications?

Here are 5 related questions:
1. What is the general form of the equation for a vertical line?
2. How do you find the slope of a vertical line?
3. Can there be multiple values of \( x \) for a vertical line equation?
4. How would the graph of this equation look on a Cartesian plane?
5. What happens if the y-coordinate is changed to a positive value?

**Tip:** For vertical lines like \( x = -8 \), the slope is undefined because the line moves straight up and down.

Plot the point on the line with the y-coordinate y = -7 for the equation x + 8 = 0.
