X Question (G. SRT. A.)
What are the coordinates of point A’, the image of point
A(1,-3) after the composite transformation R90 • r y = x
where the origin is the center of rotation?
**HINT**
The circle means "composite"
In a composition you do the second direction FIRST
(reflection) and the first direction 2nd (rotation)
a) (3,-1)
b) (3,1)
c) (-1,-3)
Tisor
y=x
Do Second e Do First
