The axis of symmetry of a parabola is a vertical line that passes through its vertex, dividing the parabola into two symmetric halves. For a parabola with a vertex at (-1, 6), we focus on the x-coordinate of the vertex.

In this case:

The vertex is at the point (-1, 6), where -1 is the x-coordinate and 6 is the y-coordinate.

Since the x-coordinate of the vertex is -1, the axis of symmetry is defined by t...
