Question

the coordinate point q(0,10) is reflected over the y - axis. identify the x - and y - coordinates of its image, q. (1 point)
the coordinates of q are (0, 10) after a reflection over the y - axis.
the coordinates of q are (-10, 0) after a reflection over the y - axis.
the coordinates of q are (10, 0) after a reflection over the y - axis.
the coordinates of q are (0, -10) after a reflection over the y - axis.

Explanation:

Step1: Recall reflection rule

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

Step2: Apply rule to point Q

For point $Q(0,10)$, $x = 0$, $y=10$. After reflection over y - axis, $-x = 0$, $y = 10$. So $Q'$ is $(0,10)$.

Answer:

The coordinates of $Q'$ are $(0,10)$ after a reflection over the y - axis.
