If I reflect ΔXYZ across the x-axis, what is the second step to drawing the reflection?

• Connect all of the dots

• Plot each new point the same number of units from the line of reflection

• Count the number of units each point is from the line of reflection

Which reflection does the image show?

• Reflection across the x-axis according to the rule (x, y) → (x, −y)

• Reflection across the y-axis according to the rule (x, y) → (x, −y)

• Reflection across the x-axis according to the rule (x, y) → (−x, y)

• Reflection across the y-axis according to the rule (x, y) → (−x, y)
