The vertices of a triangle are P[4.1). Q(2.-8), and R(-8.1). What are the vertices of the image reflected across the y-axis? O A P14.-1), Q12,8), and RX-8.-1)
B. PY-4. 1). Q1-2.-8), and R(8.1)
OC. P(-4,-1). QT-2,8), and R18.-1)
OD. P14.1). Q12.-8), and R1-8.1)

Given:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).

To find:

The vertices of the image reflected across the y-axis.

Solution:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.

If a figure is reflected across the y-axis, then

Using this rule, we get

So, the vertices of the image are .

Therefore, the correct option is B.

Note: Options are not in proper form.
