Question

The original point is (-7, 2), what is the new point after a reflection across the x-axis?

Answer 1

Answer: I think the reflection would be (-7,-2)

Step-by-step explanation:

The rule of a reflection over the x-axis is that the x remains the same but the Y becomes it’s opposite (the sign is changed)

Answer 2

Answer:

(-7,-2)

Step-by-step explanation:

Graphed on the Cartesian plane.

+ represents original

o represents reflected.

Both points are at x = -7. When reflected across the x-axis, the point is seems to have moved lower than from its original position.
