How to reflect the object over the y axis

Step-by-step explanation:

The transformation required is a reflection across y-axis.

According to the rules of transformations, to reflect a figure, we have to multiply a variable by "-".

If we want to reflect across the x-axis, we have to change each y-value to its opposite.

If we want to reflect across the y-axis, we have to change each x-value to its opposite.

So, in this case, by multiplying each x-coordinate by "-", we'll obtain the reflection.

From the graph, we see that coordinates of the figure are

X(-1,3)

Y(2,1)

Z(-3,-3)

So, the coordinates of the reflected figure are

X'(1,3)

Y'(-2,1)

Z'(3,-3)
