Question

question 6 of 10 if △abc is reflected across the y - axis, what are the coordinates of a? a. (1, - 3) b. (-1, 3) c. (5, - 3) d. (-1, - 3)

Explanation:

Step1: Identify original coordinates of A

From the graph, the coordinates of point A are (1, 3).

Step2: Apply reflection rule across y - axis

The rule for reflecting a point (x, y) across the y - axis is (-x, y). For point A(1, 3), when reflected across the y - axis, x = 1 changes to - 1 and y = 3 remains the same. So the coordinates of A' are (-1, 3).

Answer:

B. (-1, 3)
