Question

The point A(4, –1) is reflected over the x-axis. Use a mapping to find the coordinates of A’. A’(4, –1) A’(–4, –1) A’(4, 1) A’(–4, 1)

Answer 1

c

Answer 2

(C) A'(4, 1)

Explanation:

When a point is reflected across the x-axis, the following happens

• The x-coordinate remains the same
• The y-coordinate is transformed into its opposite (its sign is changed).

Given the Point A(4, –1)

When it is reflected, following the rules above

• The x-coordinate remains 4
• The y-coordinate changes from -1 to 1.

The coordinates of A' will therefore be: A'(4,1)
