Answer:
4
Step-by-step explanation:
<em>When rotating a point 90 degrees counterclockwise about the origin the point A(x,y) becomes A'(-y,x). </em>
Point C has coordinates of (4, 3)
New coordinates will be C'(-3, 4)
<u>So the answer is:</u>
y-coordinate of C' is 4
Answer:
so whats the question. ...........
X=1.2
y=-10.7
-x+(-y)=-(1.2)+(-(-10.7)=-1.2+10.7=9.5
Answer: -x+(-y)=9.5
I think 2) but not so sure
