19° I'm not completely sure but I think this is it
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.
Answer:
well if you look at it there is no m so how would you even know...
