Question

Pentagon VWXYZ is shown on the coordinate grid. A student reflected pentagon VWXYZ across the x-axis to create pentagon V’W’X’Y’Z’.




Which rule describes this transformation?


A

(x,y)---(x,-y)


B

(x,y)---(x,y+8)


C

(x,y)---(-y,x)


D

(x,y)---(-x,y)

Answer 1

Reflecting across the x axis maintains the same x coordinate, but changes the sign of the y coordinate.

So, the transformation is

$(x,y)\mapsto (x,-y)$

Answer 2

The rule described the transformation is (x, y)-(x, -y).

Given that,

Pentagon VWXYZ is shown on the coordinate grid.

A student reflected pentagon VWXYZ across the x-axis to create pentagon V’W’X’Y’Z’.

We have to determine,

Which rule describes this transformation.

According to the question,

One can perform different operations on any image in a plane to transform it.

In the process of transformation, an object can change its size, position, or orientation.

It involves taking a pre-image of an object and producing its image with a transformation of some sort.

After rotation in pentagon VWXYZ across the x-axis to create pentagon V’W’X’Y’Z’.

The coordinate after rotation in the pentagon the coordinate (x, y) transformation into (x, -y).

Hence, The rule described the transformation is (x, y)-(x, -y).
