To find the equation of the vertical line of reflection for the octagon plotted in quadrant 2, we need to determine the x-coordinate that would be the axis of symmetry.
Since the octagon is symmetrical and plotted in quadrant 2, the line of reflection should be halfway between the leftmost and rightmost points of the octagon.
If the leftmost vertex has an x-coordinate of \( a \) and the rightmost vertex has an x-coordinate of \( b \), the vertical line of reflection can be found using the formula:
\[ x = \frac{a + b}{2} \]
Without specific coordinates for the vertices, I can't provide a numeric answer. However, you can apply this formula directly to the x-coordinates you have.
Therefore, the final equation for the vertical line of reflection would be:
\[ x = \text{(value calculated from the coordinates)} \]
If you have specific coordinates of the vertices, please provide them, and I can help you calculate the exact equation.
