Search this up "If the point z (6,-9) is rotated 180° around the origin, what are the new coordinates of point Z ?"
Free points also respond if you did it.

Z' (-6,9)

Step-by-step explanation:

When a point is rotated around 180 degrees, the negative and plus values are simply switched, so positive 6 becomes -6, and -9 became positive 9.

Hope this helps :)

(-6, 9)

Step-by-step explanation:

For 180 degrees, the rule is (x, y) > (-x, -y)

we rotate the point (6,-9) > (-6, --9) =(-6, 9)

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
