Question

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? I think its P(4,-1) q(2,8) andR(-8,-1)

Answer 1

good guess, but no. you need to flip x coordinates instead

Answer 2

P(4,1) ---> P'(-4, 1)

Answer 3

oh shoot. Alright thanks

Answer 4

you figured out the remaining coordinates ?

Answer 5

Indeed, I got (-2, -8) (-8,1)

Answer 6

Q is correct
R isn't
