Reflection of X and Y Axis

Graph the points (-3, 2) (-6, 3) and (-4,6). Reflect the image over the y axis and graph the new points. You should graph a total of 6 points.

Identify the coordinates of the image with a REFLECTION over the y-axis.

• (6,6)

• (3,6)

• (8,3)

• (5,3)

• (-3,5)

• (-6,6)

• (3,8)

When a coordinate reflects over the x-axis the y-coordinate...

• changes to its opposite sign

• stays the same

What is the rule for a reflection over the y-axis?

• (x,y)→(-x,y)

• (x,y)→(x,-y)

• (x,y)→(-x,-y)

• (x,y)→(y,x)

Reflect the point over the x-axis. What is the coordinate of its image?

• (-3,3)

• (3,3)

• (-3,-3)

• (3,-3)

If you reflect point (-2,7) over the y-axis, what is its image point?

• (2,7)

• (2,-7)

• (-2,-7)

• (7,-2)

If you reflect point (-2,7) over the x-axis, what is its image point?

• (2,7)

• (2,-7)

• (-2,-7)

• (7,-2)

If a point remains unchanged after a reflection, then it lies on...

• the line of symmetry

• itself

• the origin

• point (5,6)

What is point D (4, -5) reflected over both axes?

• D'( -5,4)

• D'(-4, 5)

• D'(9, 0)

• D'(-4, -5)

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

• y-coordinate

• x-coordinate

• y-axis

• x-axis
