What is the equation for the line of symmetry in this figure?
x=3
y=0
x=0
y=3

The line of symmetry for this figure is

Step-by-step explanation:

Step 1:

First, we need to determine if the line of symmetry is vertical or horizontal.

The line of symmetry for this figure is horizontal.

Since the line is horizontal, its equation will be of the form,

So the options and cannot be the answers.

Step 2:

The option would mean the line of symmetry is the x-axis itself.

Since the line of symmetry is 3 units above the x-axis, the line of symmetry for the given figure is

the answer will be
