Step-by-step explanation:
Which transformations could have taken place? Select two options.
1 answer:
The two options are R₀ 270 , R₀ 90 , Option C and D .
The complete question is attached in the image.
<h3 /><h3>What are the two types of Transformations ?</h3>There are two types of transformations namely , Rigid Transformation and Non- Rigid Transformation
The rigid transformations do not change the shape and size of the preimage .
The non Rigid transformation do not change the shape but change the size of the preimage.
The rule rotating the origin , 270 degree is
(x,y) ----> (y , -x)
as (x,y) is (0,5)
Therefore after 270 degree transformation
(y,-x) is (5 , 0)
So, the clockwise rotation is 90 degree about origin
(x,y) ----> (y , -x)
as (x,y) is (0,5)
Therefore after 90 degree transformation
(y,-x) is (5 , 0)
Therefore the two options are R₀ 270 , R₀ 90 , Option C and D .

Answer:
The points (4,11), (6,14), (30,50) lie on the line joining the points (0,5) and (2,8).
Step-by-step explanation:
The equation of the line passing through two points and
is
So, the equation of the line passing through two points (0,5) and ( 2, 8 ) is
For the point (4,11), pout x=4 in equation (i), we have
, which is given y coordinate, hence this point (4,11) lies on the line.
For the point (5,10), pout x=5 in equation (i), we have
which is not the given y coordinate, hence the point (5,10) doesn't lie on the line.
For the point (6,14), pout x=6 in equation (i), we have
, which is the given y coordinate, hence the point (6,14) lies on the line.
For the point (30,50), pout x=30 in equation (i), we have
, which is the given y coordinate, hence the point (30,50) lies on the line.
For the point (40,60), pout x=40 in equation (i), we have
, which is not the given y coordinate, hence the point (40,60) doesn't lie on the line.
Hence, the points (4,11), (6,14), (30,50) lie on the line joining the points (0,5) and (2,8).
