Question

Point A is reflected across the y-axis to get B and across the x-axis to get C. If the coordinates of B are (3,4), find the coordinates of C.

• A. C(-3,4)
• B. C(3,-4)
• C. C(-3,-4)
• D. C(3,4)

Answer 1

The correct option is C C(-3,-4)

Point A is reflected across y-axis to get B(3,4).

Hence, if the point B(3,4) is reflected across y-axis, we should get Point A.

Plotting Point A in this manner, we find:


Hence, the coordinates of Point A are A(-3,4).

Now, Point C is the reflection of Point A across x-axis. So, plotting C, we get:


Hence, the coordinates of Point C are C(-3,-4).
