Question

rotating a point (2, 7) 270 degrees clockwise around the origin will move it to what coordinates?
a. (-2,7)
b. (7,-2)
c. (2,-7)
d. (-7,2)

Explanation:

Step1: Recall 270° clockwise rotation rule

A 270° clockwise rotation around the origin transforms a point $(x,y)$ to $(y,-x)$.

Step2: Substitute $x=2, y=7$

Substitute the values into the rotation formula: $(7, -2)$

Answer:

b. (7,−2)
