Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis. (4 points)

Missing part of the question:

Triangle PQR is transformed to triangle P'Q'R'. Triangle PQR has vertices P(4, 0), Q(0, −4), and R(−8, −4). Triangle P'Q'R' has vertices P'(1, 0), Q'(0, −1), and R'(−2, −1).

Step-by-step explanation:

Given

PQR

P'Q'R'

Transformation: y-axis reflection

Required

Determine the coordinates of P"Q"R"

When a point (x,y) is reflected across the y axis, the new point becomes:  (-x,y)

So, we have:

---->

---->

----->

So, the coordinates of P"Q"R" is:
