Question

Triangle is reflected over a horizontal line of reflection to create triangle . What are the coordinates of vertex ?
A.( -3, - 9)
B. (-3 , -7 )
C. (-2 , -2 )
D. ( 3, - 9)

Answer 1

To determine the coordinates of a vertex after a reflection over a horizontal line, we need to know the original coordinates and the line of reflection. Since you have provided options without specifying the original coordinates or the line of reflection, we can't directly find the answer.

However, if we denote the original vertex of the triangle as \((x, y)\) and the horizontal line of reflection as \(y = k\), the reflected vertex would be at the coordinates \((x, 2k - y)\).

If you can provide more details, such as the coordinates of the original vertex and the equation of the horizontal line of reflection, I can help you determine the correct answer from the choices you've provided.
