What are the coordinates of the image of vertex f after a reflection across the line y = –x? (–1, –3) (3, –1) (1, 3) (–3, 1)

(3,1) (1,-3) (-3,-1) (-1,3)

Step-by-step explanation:

When you reflect across y= -x then you swtich the places of the coordinates (x becomes y and y become x) and then change their signs

ex. (-1, -3)

Step one: Switch places (-3, -1)

Step two: Change their signs (3, 1)

(-1,-3)

Step-by-step explanation:

big brain

thats one

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
