Question

e is the image of the point e after a reflection.
e(-10,10)→e(-10,-10)
over which axis was point e reflected?
x - axis y - axis

Explanation:

Step1: Recall reflection rules

When reflecting a point \((x,y)\) over the \(x\) - axis, the rule is \((x,y)\to(x, - y)\). When reflecting over the \(y\) - axis, the rule is \((x,y)\to(-x,y)\).

Step2: Apply the rules to the given points

For point \(E(-10,10)\) and its image \(E'(-10, - 10)\), the \(x\) - coordinate remains the same (\(x=-10\) for both \(E\) and \(E'\)), and the \(y\) - coordinate changes sign (\(y = 10\) for \(E\) and \(y=-10\) for \(E'\)).

Answer:

x - axis
