Answer:
<h2>The x-coordinate after the rotation is -10.</h2>Step-by-step explanation:
A 810° rotation is equal to a 90° rotation. So, the transformation described gives the same result than rotating 90° only.
A 90° counterclockwise rotation is defined by the rule
The given coordinate is . Using the rule, we have
Therefore, the x-coordinate after the rotation is -10.
The best way to solve this problem is by plugging in each answer choice for both equations and seeing which one works. You can already see that choice A doesn't work because -1 is not greater than or equal to 4. That means you just need to test choices B and C!
Choice B (4, -2)
2 is not greater than or equal to 6, so choice B doesn't work.
Choice C (4, 2)
Since 6 is equal to 6 and 4 is equal to 4, choice C works!
-------
Answer: C) (4, 2)
Choice B (4, -2)
2 is not greater than or equal to 6, so choice B doesn't work.
Choice C (4, 2)
Since 6 is equal to 6 and 4 is equal to 4, choice C works!
-------
Answer: C) (4, 2)
