Respuesta :

A reflection over the x-axis is given by:

[tex](x,y)\rightarrow(x,-y)[/tex]

A reflection over the y-axis is given by:

[tex](x,y)\rightarrow(-x,y)[/tex]

A rotation of 180° is given by:

[tex](x,y)\rightarrow(-x,-y)[/tex]

The coordinates of point B are (-1,4) if we perform the transformations stated above we get:

[tex](-1,4)\rightarrow(-1,-4)\rightarrow(1,-4)\rightarrow(-1,4)[/tex]

Therefore, the coordinates of B' are (-1,4)
