Given the point:
(x, y) ==> (9, 2)
Let's find the new point of the image after a rotation of 90 degrees counterclockwise about the origin.
To find the image of the point after a rotation of 90 degrees counterclockwise, apply the rules of rotation.
After a rotation of 90 degrees counterclockwise, the point (x, y) changes to (-y, x)
Thus, we have the point after the rotation:
(x, y) ==> (-y, x)
(9, 2) ==> (-2, 9)
Therefore, the image of the points after a rotation of 90 degrees counterclockwise is:
(-2, 9)
ANSWER:
(-2, 9)
Answer:
B is true.

Answer:
See below
Step-by-step explanation:
In math, the distance formula gives us the distance between two
points, (x₁, y₁) and x₂, y₂):
For example, in the triangle below, the distance between the points (1,5) and (-2, 1) is
= 5
You are really using Pythagoras' Theorem to find the distance.
When using the distance formula, you are building a right triangle whose hypotenuse connects two given points.
