Question

1. when a point is reflected on the y - axis, what changes?

neither x nor y
coordinate
the y - coordinate
the x - coordinate
both x and y
coordinates

Explanation:

When reflecting a point \((x,y)\) over the \(y -\)axis, the rule is \((x,y)\to(-x,y)\). This means the \(x -\)coordinate changes its sign (its value changes in terms of being positive or negative), while the \(y -\)coordinate remains the same.

Answer:

C. The x - coordinate
