Question

True or False
When point E (-9, 3) is rotated 180° about the origin, its coordinate becomes (3, 9).

Answer 1

1. Get a graph paper
2. Plot the two points
3. Connect them to the origin
4. Judge

Answer 2

i got True is that right

Answer 3

if you subsitute the rotation matrix for 180 degrees you would get the rule
T180(x,y)=(-x,-y), so the rotated point should be (9,-3)

Answer 4

ohh so it would be False

Answer 5

Would you please stop guessing lol

Answer 6

:p

Answer 7

if the rotated point is 9, -3 would it be False
