Question

a point with a positive x - coordinate and a negative y - coordinate is reflected over the y axis. which sentence describes the coordinates of the new point? the x - coordinate is positive, and the y - coordinate is negative. the x - coordinate is negative, and the y - coordinate is positive. the x - coordinate is positive, and the y - coordinate is positive. the x - coordinate is negative, and the y - coordinate is negative.

Explanation:

Step1: Recall reflection rule

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

Step2: Analyze given point

The original point has $x>0$ and $y < 0$. After reflection over the y - axis, the x - coordinate becomes $-x<0$ (since $x>0$) and the y - coordinate remains $y<0$.

Answer:

The x - coordinate is negative, and the y - coordinate is negative.
