Question

Answer 1

Answer:

B

Step-by-step explanation:

Answer 2

Answer:

$(x, y) \rightarrow (-x, -y)$

Step-by-step explanation:

Rotation of any point in the form of (x, y) about the origin O through 180 degree in anticlockwise or counterclockwise direction, it will takes the new position (-x, -y)

i.e,

The rule of rotation about the origin through 180 degree is given by:

$(x, y) \rightarrow (-x, -y)$

For example:

Let the point A(-4, 6) rotate by the rule $R_{0, 180^{\circ}}$

then;

$A(-4, 6) \rightarrow (4, -6)$

⇒the coordinate of  image of the point A is, (4, -6)

Therefore, the rule represents $R_{0, 180^{\circ}}$  is, $(x, y) \rightarrow (-x, -y)$
