Question

B' (-3,-4) is the image of B after a reflection in the y-axis,What are the coordinates of B?

Answer 1

Answer:

The coordinates of B will be (3,-4).

Step-by-step explanation:

If a point on the coordinate plane reflects across the y-axis then its y-coordinate will not alter but the x-coordinate will change by its sign only.

Now, if B'(-3,-4) is the image of B after a reflection in the y-axis then we can say B is the image point when the original point is B'(-3,-4) after reflection in the y-axis.

Therefore, the coordinates of B will be (3,-4). (Answer)
