Question

1. when a figure is reflected over the y - axis, what happens to its x - coordinates? they remain same they are doubled they change sign they are halved

Explanation:

When reflecting a point \((x,y)\) over the \(y -\)axis, the transformation rule is \((x,y)\to(-x,y)\). This means the \(x -\)coordinate changes its sign. For example, if we have a point \((3,4)\) and reflect it over the \(y -\)axis, it becomes \((- 3,4)\).

Answer:

They change sign
