Question

Point A, located at (-11, -7) on the coordinate plane, is reflected over the x-axis to form

point B. Then point B is reflected over the y-axis to form point C. What are the coordinates
of points B and C?
Point B: (-11,7)
Point C: (11,7)
Point B: (-11,7)
Point C: (11, -7)
Point B: (11,-
Point C: (11,7)
Point B: (11, -7)
Point C: (-11,7)

Answer 1

Sorry but I don't know the answer.

Answer 2

Explanation:

Given that,

NOTE: Reflection law

If point (x , y) reflected across the x-axis, then its image is (x , -y)

If point (x , y) reflected across the y-axis, then its image is (-x , y)

Point A = (-11, -7)

Point A is reflected over x axis to form point B.

This shows that, the x coordinate did not change but the y coordinate moves from one quadrant to the adjacent quadrant.

Therefore, point B is (-11, 7)

Also, point B is reflected over y axis to form point C.

Same as above, the y axis doesn't change but the x axis is reflected to the other side

Then, point C is (11, 7).

Then, the correct answer is option A

Point B: (-11, 7)

Point C: (11, 7)
