Question

What is the image of left bracket, minus, 1, comma, minus, 4, right bracket ( − 1 , − 4 ) (−1,−4) after a reflection over the x-axis?

Answer 1

The image of (-1, -4) after a reflection over the x-axis is (-1, 4)

Explanation:

When you reflect a point over the x-axis, you change the sign of the y-coordinate while keeping the x-coordinate the same. So, for the point (-1, -4), the image after a reflection over the x-axis would be:

(-1, -(-4)) = (-1, 4)
