Question

after rotating a point (7,5) 180 degrees around the origin, where will it be located?
a. (-7,5)
b. (5,-7)
c. (-7,-5)
d. (7,-5)

Explanation:

Step1: Recall 180° rotation rule

For a point $(x,y)$, rotating 180° around the origin transforms it to $(-x,-y)$.

Step2: Apply rule to (7,5)

Substitute $x=7$, $y=5$: $(-7, -5)$

Answer:

c. $(-7,-5)$
