Question

what are the coordinates of the image of vertex f after a reflection across the line y = -x? (3, -1) (1, 3) (-3, 1) (-1, -3)

Explanation:

Step1: Identify original coordinates of F

Given F(1, -3)

Step2: Apply reflection rule over y=-x

For (a,b), reflection is (-b,-a). Here, a=1, b=-3: (-(-3), -1)=(3,-1)

Answer:

(3, -1)
