Triangle ABC has vertex coordinates A5 2 B1 3 and C1 1 It is rotated 90 clockwise around the origin What are the coordinates of B class=

Respuesta :

Answer:

(3,1)

Step-by-step explanation:

The rule for a 90 degree clockwise rotation:

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

B is (-1, 3).

Apply the rule:

[tex]\frac{(-1,3)\rightarrow\boxed{(3,1)}}{(x,y)\rightarrow(y,-x)}\\\\3 * 1 = 3\\\\-1 * -1 = 1[/tex]

Option D should be the correct answer.
