Question

1. if a triangles vertices are reflected across the x - axis, which transformation occurs? (-x,y) (x,-y) (-x,-y) (y,x)

Explanation:

Step1: Recall the rule for reflection across the x - axis

When a point \((x,y)\) is reflected across the \(x\) - axis, the \(x\) - coordinate remains the same and the \(y\) - coordinate changes its sign.

Step2: Apply the rule to the general point

If the original point is \((x,y)\), after reflection across the \(x\) - axis, the new point is \((x, - y)\)

Answer:

\((x,-y)\)
