Answer:

D.

Step-by-step & Reason explanation: This is really a general answer, it is actually really easy to answer. What you'd do is take whatever shape (like triangle ABC) and flip it over. When the question asks over the y-axis, you'll just flip it over to that side. I'm not sure if that made any since. But, think of it as a butterfly. You'll just throw it to the side the axis represents.

Thanks!

Answer:

The correct option is 3.

Step-by-step explanation:

If the triangle ABC reflected over the y-axis, then

[tex](x,y)\rightarrow (-x,y)[/tex]

From the given figure it is noticed that the vertices of triangle ABC are A(1,1), B(3,4) and C(3,1).

The vertices of image are

[tex]A(1,1)\rightarrow A'(-1,1)[/tex]

[tex]B(3,4)\rightarrow B'(-3,4)[/tex]

[tex]C(3,1)\rightarrow C'(-3,1)[/tex]

The vertices of the image are A'(-1,1), B'(-3,4) and C'(-3,1). Therefore option 3 is correct.
