1. reflecting a shape over the line y = -x results in:

a. a scaled shape
b. a shape with swapped and negated coordinates
c. a shape with doubled coordinates
d. a rotated shape

Explanation:

When reflecting a point $(x,y)$ over the line $y = -x$, the transformation rule is $(x,y)\to(-y,-x)$. This means the coordinates are swapped and negated. It is not scaling (changing size), doubling coordinates, or a simple rotation.

Answer:

B. a shape with swapped and negated coordinates
