Question

Christo graphs AB with endpoints A( -3, -2 ) and B ( -1, -2 ) what are the endpoints of the image after a reflection of AB across the x axis?

1. (-3,2) and (-1,2)

2.(-3.-2) and (-1,-2)

3. (1,-2) and (3,-2)

4. (2,3) and (2,1)

5. none of the above

Answer 1

(-3,2) and (-1,2)

Step-by-step explanation: I took the test already and got this correct crazy to find this question 2 days later.

Answer 2

• 1. (-3,2) and (-1,2)

Explanation:

Reflection over x-axis results in coordinate change as follows:

• (x, y) → (x, -y), x-coordinate stays as is and y-coordinate changes its sign to opposite

Given points:

• A(-3, -2) and B(-1, -2)

The image of AB will have coordinates:

• A'(-3, 2) and B'(-1, 2)

Correct choice is 1.
