The image of the point (1, -2) after a rotation of 180° about the origin is

(-2, 1)
(2, -1)
(-1, 2)

(-1,2)

Step-by-step explanation:

Found answer on .

(-1,2)

Step-by-step explanation:

In this problem, the signs are switched because there is a rule to 180 rotation that is (x,y) to (-x,-y).

(1,-2)×(-1x, -1y)= (-1,2) .

if both points were negative, the points would be positive. if they were positive, they would be negative.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
