If (4, -5) is reflected across the x-axis, what would be the new ordered pair?

reflection across the x-axis takes (x,y) → (x,-y) so ...

(4,-5)

What is the reflection of (- 3/5 across the x-axis?

To reflect a point across the x-axis, we need to change the sign of the y-coordinate while keeping the x-coordinate the same.

Given the point (4, -5), to reflect it across the x-axis, we simply change the sign of the y-coordinate to positive.

Therefore, the new ordered pair would be (4, 5).
