Reflections of Points in Coordinate Plane

In which quadrant is the REFLECTION of point P in the coordinate plane?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

The points are reflections of each other across the x-axis.

• True

• False

Reflections over the x-axis change the ____-__________. 

• y-coordinate

• x-coordinate

• y-axis

• x-axis 

What does this show?

• reflection over the y-axis

• reflection over the y-coordinate

• reflection over the x-axis 

• reflection over the x-coordinate

The point (a, b) is reflected over the x-axis, then the y-axis, then the y-axis again, and then the x-axis again. What are the coordinates of the new point?

• (−a, b)

• (−a, −b)

• (a, −b)

• (a, b)

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

Match the following algebraic representation to the verbal description.

• Reflect over the x-axis

• to the right 4 units and down 2 units

• Reflect over y-axis

• (x + 4, y - 2)
