What is the line of symmetry?

x= -10 (you need to enter as well the variable "x" and the equal sign since they want the complete equation of the vertical line of symmetry)

Step-by-step explanation:

Notice that this equation corresponds to a parabola given in vertex form, with vertex at x = -10, and y = -6.

Such parabola would have an axis of symmetry as a vertical line going through the vertex. Such vertical line should therefore be of the form: x = -10

x = -10

Step-by-step explanation:

Line of symmetry of any quadratic is x = h, where h is the x-coordinate of the turning point

For the given quadratic, turning point is at (-10,-6)

Line of symmetry: x = -10
