Question

the rectangualr below will be reflected across the y-axis . What is the new coordinates of point X? ​

Answer 1

a.) (-5,4)

Explanation:

(x, y)

Reflection of a Point in x-axis: (-x, y)

Reflection of a Point in y-axis: (x, -y)

Reflection of a Point in origin: (-x, -y)

We have the point X(5, 4).

Therefore

the new coordinates of the point X in reflection across y-axis is (-5, 4).

Answer 2

(-5, 4)

Explanation:

(x, y)

Reflection of a Point in x-axis: (-x, y)

Reflection of a Point in y-axis: (x, -y)

Reflection of a Point in origin: (-x, -y)

We have the point X(5, 4).

Therefore

the new coordinates of the point X in reflection across y-axis is (-5, 4).
