It is 6 because 3x3=9 then you do the same for 2 so 6/9
The coordinates of triangle A′B′C′ is A′(2, 1), B′(1, 2), C′(3, 2)
On plotting the coordinates on the graph, it is found :
Option A is the coordinates of a straight line.
Option C is the coordinates of a bigger triangle
Option D has a different shape.
Only option B fulfills the required condition of similar shape and scale factor of 0.5 .
Vertices of a triangular garden:
A(4,2)
B(2,4)
C(6,4)
Scale factor = 0.5
What are the coordinates?
- A coordinate system in geometry is a system that uses one or more numbers, or coordinates, to determine the position of points or other geometric elements on a manifold such as Euclidean space.
- Coordinates are numerical distances or angles that uniquely identify points on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematicians, scientists, and engineers use a variety of coordinate schemes.

Answer:
B 1 1/7
Step-by-step explanation:
- 9 2/7 - ( -10 3/7)
We know subtracting a negative is like adding
- 9 2/7 +10 3/7
10 3/7 - 9 2/7
Putting this vertical
10 3/7
-9 2/7
-----------------
1 1/7
