Question

The point (4,1) is reflected over the line y=-x to create Point B. What are the coordinates of B? O (-1,-4) 0 (-1,4) O (1,-4) O (1,4)

Answer 1

we know that

The rule of the reflection across the line y=-x is equal to

(x,y) -------> (-y,-x)

so

(4,1) -----> (-1,-4)

therefore

the answer is

(-1,-4)
