Question

What is the y-coordinate of the image of P(3,-4) after a reflection in the x-axis?

Answer 1

`\boxed{4}`

Explanation:

When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign.

Thus, the y-coordinate becomes
`\boxed{\textbf{4}}`.
