Answer:
A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)
Step-by-step explanation:
The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).
The mapping for a rotation through 90° clockwise about the origin is
Therefore:
Therefore the image rectangle has coordinates:
The first choice is correct.
Add all of them together
You have to add the numbers and that gives you the sum
a + 7
so "a" is 4 so
4+7=11
Hope this helps!
