Question

Reflect (7, 3) in (a) the x-axis and (b) the y-axis

Answer 1

Answer:

In x-axis: $(7,-3)$, In y-axis: $(-7,3)$

Step-by-step explanation:

The rule of the reflection of a point across the x-axis is as shown:

The reflection of the point $(x,y)$ across the x-axis is given by $(x,-y)$.

The point given to us is $(7,3)$, when reflected across the x-axis we get:

$(x,-y)=(7,-3)$

Now, when a point $(x,y)$ is reflected across the y-axis we get the point $(-x,y)$.

So when the point $(7,3)$ is reflected across the y-axis we get: $(-x,y)=(-7,3)$.
