98 Points, Will mark brainliest aswell. Need in next 10 minutes or no brainliest.

Answer 1

The y-axis is behaving like a mirror in the graph.

If you stand at where ABCD is and a mirror is placed along the y-axis, your image will be at where A'B'C'D' is.

Therefore this is a reflection in the y-axis or in the line
$x = 0$
For reflection in the y-axis, we negate the x-coordinates.


The rule for this reflection in the y-axis is


$rx - axis(x,y)\rightarrow (-x,y)$

Answer 2

The option $\bf{A}$  is correct match for the reflection of object $ABCD$.

Further explanation:

Concept:

The formula for the reflection of a point is as follows:

If a point $\left( {x,y} \right)$ is reflected across $y$ axis its $x$ coordinate becomes negative as follows:

$rx-{\text{axis}}\left( {x,y}\right)\to \left({-x,y}\right)$

If a point $\left( {x,y} \right)$ is reflected across $x$ axis its $y$ coordinate becomes negative as follows:

$ry-{\text{axis}}\left({x,y}\right)\to\left({x,-y}\right)$

Explanation:

From the given graph, it is observed that $y$-axis of the plane $xy$ is behaving like a mirror.

If we stand in place of $ABCD$ and a mirror is placed along the $y$-axis, our image will be in place of $A'B'C'D'$.

Therefore this is a reflection in the $y$-axis or in the line $x = 0$.

For reflection in the $y$-axis, the $x$ coordinate becomes negative.

The rule for this reflection in the $y$-axis is as follows:

$rx-{\text{axis}}\left({x,y} \right)\to\left({-x,y}\right)$.

Thus, the option $\bf{A}$ is correct match for the reflection of object $ABCD$.
