Verified Answer :

Reflection of point U across y-axis = (1, -5)

why . . .

reflection across y-axis means to take the negative of the x-value, and since point U has coordinates (-1, -5), the negative of -1 is 1, then the reflected coordinate must be (1, -5)

Answer:

B. \((1,-5)\)

Step-by-step explanation:

We have been coordinates of some points on coordinate plane. We are asked to find the reflection image of U across the y-axis.

We know that after reflecting a point across y-axis, the y-coordinate of point remains same, while x-coordinate changes to its opposite sign.

We can see that coordinates of point U are \((-1,-5)\). After the reflection across y-axis the y-coordinate will remain same that is \(-5\), while x-coordinate will be opposite of \(-1\) that is \(-(-1)=1\)

Therefore, the coordinates of point U after reflection across y-axis would be \((1,-5)\) and option B is the correct choice.
