Question

What is the equation for the line of symmetry in this figure?

Please explain how to get the answer because I don't know how and I need to answer the rest of these questions. Thanks!

Answer 1

The line of symmetry is along the x-axis but it's moved 3 units up.

Step-by-step explanation:

• middle of figure is three units from the x-axis
• equation is x+3=line of symmetry

Answer 2

y=3

Step-by-step explanation:

The line of symmetry is the line along which the figure could be rotated and nothing would change (the orig. figure and the reflected figure would overlap completely). You see the midpoint of the left side of the figure is (-2,3) while the midpoint of the right side of the figure is (1,3). This would make the line passing through these two y = 3
