HURRY PLEASE!!!!! Triangle RST is translated 2 units left and then reflected over the y-axis.
AVprozaik [17]

Answer:

The correct options are 1 and 2.

Step-by-step explanation:

The vertices of triangle are S(-4,4), T(-1,4), R(-1,1).

If triangle translated 2 units left,

(x,y)\rightarrow (x-2,y)

and then reflected over the y-axis,

(x-2,y)\rightarrow (-x+2,y)

The relation between image and preimage is

(x,y)\rightarrow (-x+2,y)                          ..... (1)

The vertices of image are

S(-4,4)\rightarrow S'(6,4)

T(-1,4)\rightarrow T'(3,4)

R(-1,1)\rightarrow R'(3,1)

Therefore the vertices of image are S'(6,4),T'(3,4), R'(3,1).

1. A reflection over the y-axis and then a translation 2 units right is defined as

(x,y)\rightarrow (-x+2,y)

It is equivalent to relation 1, therefore option 1 is correct.

2. A 180 rotation about the origin, then a translation 2 units right, and then a reflection over the x-axis is defined as

(x,y)\rightarrow (-x+2,y)

It is equivalent to relation 1, therefore option 2 is correct.

3. A reflection over the y-axis and then a translation 2 units left is defined as

(x,y)\rightarrow (-x-2,y)

It is not equivalent to relation 1, therefore option 3 is incorrect.

4. A 180 rotation about the origin, then a translation 2 units left, and then a reflection over the x-axis is defined as

(x,y)\rightarrow (-x-2,y)

It is not equivalent to relation 1, therefore option 4 is incorrect.

5. A reflection over the x-axis and then a translation 2 units right is defined as

(x,y)\rightarrow (x+2,-y)

It is not equivalent to relation 1, therefore option 5 is incorrect.

6. A reflection over the x-axis and then a translation 2 units left is defined as

(x,y)\rightarrow (x+2,-y)

It is not equivalent to relation 1, therefore option 6 is incorrect.

Therefore the correct options are 1 and 2.
