Question

The coordinate point Q (0,-8) is reflected over the y-axis. Identify the x- and y- coordinates of its image, Q'.

The coordinates of Q' is:

a. (0,8)
b. (0,-8)
c. (8,0)
d. (-8,0)

Answer 1

When a point is reflected over the y-axis, the x-coordinate of the point changes sign, while the y-coordinate remains the same.

Given the point Q (0, -8):
- The x-coordinate is 0, which means that reflecting it over the y-axis will still result in an x-coordinate of 0.
- The y-coordinate remains -8.

Thus, the coordinates of the image Q' after reflection over the y-axis are (0, -8).

So the correct answer is:
b. (0, -8)
