Question

b is the image of the point b after a reflection. b(-7, -1) → b(7, -1) over which axis was point b reflected? x - axis y - axis

Explanation:

Step1: Recall reflection rules

Reflection over x - axis changes sign of y - coordinate. Reflection over y - axis changes sign of x - coordinate.

Step2: Analyze given points

Point $B(-7,-1)$ is transformed to $B'(7,-1)$. The x - coordinate changes sign ($-7$ to $7$) and y - coordinate remains the same.

Answer:

y - axis
