Question

If the point W(5,-4) is reflected over the x axis,

what will be the coordinates of the resulting point,
W'?

A.) -5, 4
B.) -5, -4
C.) 5, 4
D.) 4, 5

Answer 1

Given:

The point W(5,-4) is reflected over the x-axis.

To find:

The coordinates of the point W' after the reflection.

Solution:

If a point is reflected across the x-axis, then

`(x,y)\to (x,-y)`

Using this rule of reflection, we get

`W(5,-4)\to W'(5,-(-4))`

`W(5,-4)\to W'(5,4)`

The coordinates of the point W' are (5,4). The correct option is C.
