True or false: The mapping notation for reflecting point (x,y) about the x

Question

-axis is (−x,y).(1 point)
Responses

This statement is false. The mapping notation for reflecting point (x,y) about the x-axis is (y,x)..

This statement is false. The mapping notation for reflecting point (x,y) about the x-axis is (x,−y).

This statement is true.

This statement is false. The mapping notation for reflecting point (x,y) about the x-axis is (−x,−y).

Answer 1

This statement is false. The mapping notation for reflecting point (x,y) about the x-axis is (x,−y).

Answer 2

What is the mapping notation for translating point (x,y) down 3
units?(1 point)
Responses

(x+3,y)

(x,y+3)

(x−3,y)

(x,y−3)

Answer 3

The mapping notation for translating point (x,y) down 3 units is (x,y-3).

Answer 4

What translation vector translates A(−2,7) to A′(5,−1)?(1 point)
Responses

(3,−6)

(−7,8)

(7,−8)

(3,6)

Answer 5

The translation vector that translates A(-2,7) to A'(5,-1) is (7,-8).

To find the translation vector, we subtract the corresponding coordinates of A and A'.

(5 - (-2), -1 - 7) = (7, -8)

Answer 6

What is the answer

Answer 7

The answer is (7,-8).

Answer 8

Which transformation maps B(2,5) to B′(−2,−5)?(1 point)
Responses

A 270° rotation

Reflection about the y-axis

A 180° rotation

A 90° rotation

Answer 9

The transformation that maps B(2,5) to B'(-2,-5) is reflection about the origin or a 180° rotation.

Answer 10

Point (a,b) is reflected about the x
-axis. The resulting point is then reflected about the y
-axis to produce a final point. Which transformation maps the original point directly to the final point?(1 point)
Responses

A 180° rotation

A 270° rotation

A 90° rotation

A translation down b units and to the left a units

Answer 11

The transformation that maps the original point directly to the final point after a reflection about the x-axis and then a reflection about the y-axis is a 180° rotation.
