Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?(3, -4)(4, 3)(-4, -3)(-4, 3)
Question
Answer:
Step-by-step explanation:Look at the picture.Any pair of choice can be the coordinates of the rotation of the pointW (-3, 4) clockwise.All points have the same distance from the beginning.The formula of a distance between the origin and a point (x, y):[tex]d=\sqrt{x^2+y^2}[/tex]W(-3, 4)[tex]d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5[/tex](3, -4)[tex]d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5[/tex](4, 3)[tex]d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5[/tex](-4, -3)[tex]d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5[/tex](-4, 3)[tex]d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5[/tex]
