Question

which transformation would take figure a to figure b?

Explanation:

Step1: Observe the orientation

The figures are mirror - images of each other across the y - axis.

Step2: Recall transformation rules

A reflection across the y - axis changes the sign of the x - coordinates of all points while keeping the y - coordinates the same. For a point (x,y) in Figure A, its corresponding point in Figure B after reflection across the y - axis is (-x,y).

Answer:

A reflection across the y - axis.
