Figure ABCD is a rhombus with point A (3, −1). What rule would rotate the figure 270° counterclockwise?(x,y)→(−y,−x)
(x,y)→(−y,x)
(x,y)→(y,x)
(x,y)→(y,−x)

Answers

Answer 1

Answer:

Answer:

The correct option is 4.

Step-by-step explanation:

Given information: ABCD is a rhombus with point A (3, −1).

If a figure rotated 90° counterclockwise, then

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

If a figure rotated 180° counterclockwise, then

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

If a figure rotated 270° counterclockwise, then

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

Therefore the rule $(x,y)\rightarrow (y,-x)$ would rotate the figure 270° counterclockwise.

The correct option is 4.

Answer 2

Answer: (x,y)→(y,−x)

Answers

$slope = y2 - y1 / x2 - x1$

$6 - 1 / - 2 - 3$

$5 / - 5$

$- 1$

$y = mx + c$

$1 = - 1 * 3 + c$

$1 = - 3 + c$

$1 + 3 = c$

$c = 4$

$y = - 1x + 4$

$y = - x + 4$
