Question #8a1de

Answer 1

The answer is (-3, 7).

Explanation:

A reflection is basically flipping a point across the line of reflection, in this case, x=0 (the y-axis).

Think of a point as ink on paper, so when you fold the piece of paper in half, the ink is smudged onto the other side. In this analogy, the ink you've put is the original point (3, 7), the crease on the paper is the line of reflection (x=0) and the ink smudged onto the other side is the reflected point. Here's a video to help you understand it better: video explaining reflection
