Question

if you change the sign of a points x - coordinate, how does the location of the point change? the point moves down and to the left. the point crosses over the x - axis. the point crosses over the y - axis. not enough information is provided.

Explanation:

Changing the sign of a point's \(x\) - coordinate reflects the point across the \(y\) - axis. For example, if we have a point \((a,b)\) and we change its \(x\) - coordinate sign to get \((-a,b)\), the distance from the \(y\) - axis is the same but on the opposite side.

Answer:

The point crosses over the \(y\) - axis.
