Question

What is reflection of (5, 15) across the x-axis?

Answer 1

Answer:

(5 , -15)

Step-by-step explanation:

When you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.

If you are reflecting over the y-axis, then you are flipping the sign of the x-coordinate.

In this case, you are given the point (5 , 15), and you are reflecting over the x-axis, in which case, your answer will be: (5 , -15).

Answer 2

Answer:

Step-by-step explanation:

In this question, we are asked to find the point of reflection across the x-axis.

The easiest way to find reflection is to find the equal distance from the current point to the x-axis, then apply it reversely to find the reflected point.

The vertical point from (5, 15) to the x-axis is (5, 0).

Then, we need to find the distance from (5, 15) to (5, 0)

• 15 - 0 = 15 units

As we know the distance from (5, 15) to (5, 0) is 15 units, then we apply this to the other side of the x-axis by subtraction

• 0 - 15 = -15 units

Therefore, the reflected point is (0, -15)
