Question

The point (8, −15) was reflected over an axis to (−8, −15). Which axis was it reflected over? Explain.

Answer 1

Answer: it is reflected by y-axis

Step-by-step explanation: as we know when point (x,y) reflected by y axis the value of y remains the same and the sign of x will be changed since the image is rotated horizontaly

Answer 2

y-axis

Explanation:

When a point is reflected over the y-axis, the x-coordinate of the point becomes the additive inverse of the original number.

Here, (8, -15) became (-8, -15). The only change in value of the coordinates is the value of the x-coordinate, 8, which became its additive inverse, -8.

Answer: y-axis
