Question

figure j is the result of a transformation on figure i. which transformation would accomplish this? figure i figure j

Explanation:

Step1: Analyze orientation change

The orientation of Figure I is flipped to get Figure J. A reflection flips a figure over a line.

Step2: Determine reflection line

By observing the positions of the vertices, the line of reflection is the x - axis. When a point $(x,y)$ is reflected over the x - axis, it becomes $(x, - y)$.

Answer:

A reflection over the x - axis.
