5:Pretest 5 Spatial Thinking A point P has coordinates (-5, 4). What are its new coordinates after reflecting point P over the x-axis?
(-5, 4)
(-5,-4)
(5-4)
(5, 4)

Given:

The coordinates of point P are (-5,4).

Point P is reflected over the x-axis.

To find:

The new coordinates after the reflection.

Solution:

If a point is reflected across the x-axis, then the rule of reflection is:

Using this rule, we get

The new coordinates of point P after the reflection over the x-axis are (-5,-4).

Therefore, the correct option is B.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

vertical=18cm horizontal=18cm hypotenuse=25.5
