Question

Bill reflects the point (-3, 5) over the x-axis.
What is the coordinate of the new point after the reflection?
(3, 5)
(3, -5)
(-3, -5)
(-3, 5)

Answer 1

When a point is reflected over the x-axis, the x-coordinate remains the same while the y-coordinate changes sign.

For the point \((-3, 5)\):
- The x-coordinate is \(-3\).
- The y-coordinate is \(5\), which will change to \(-5\).

Thus, the new coordinates after reflecting \((-3, 5)\) over the x-axis are \((-3, -5)\).

So the coordinate of the new point after the reflection is \((-3, -5)\).
