1 multiple choice 1 point
identify the line of reflection for the image shown:
$x = -3.5$
x-axis
$y = -x$
$y = x$

Explanation:

To find the line of reflection, check the transformation of vertices. For a reflection over $y=-x$, each point $(a,b)$ maps to $(-b,-a)$. Observing the vertices of the original and reflected shapes, this mapping holds true. Other options do not match the positional relationship of the two figures: $x=-3.5$ is a vertical line, the x-axis would flip points vertically, and $y=x$ maps $(a,b)$ to $(b,a)$, which does not align with the diagram.

Answer:

$y = -x$
