Question

What is the image of (-8, -1) when it isreflected across the line y=x?A (-1, -8) C (1,8)B(1-1)D8

Answer 1

Give the object with a coordinate (-8,-1)

The transformation of an object with coordinate (x,y) reflected across the line y=x is given by

T(x,y) => (y,x)

So for the question given

If (-8,-1) is reflected across the line y = x

Then

T(-8,-1) => (-1, -8)

Answer = (-1,-8)
