Reflections (Y-Axis and X-Axis)

If point (a,b) is reflected over the y-axis, what is the resulting point?

• (a,b)

• (b,a)

• (-a,b)

• (a,-b)

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

• remains the same

• changes to its opposite sign

• becomes zero

• is doubled

What is the general rule for reflecting a point (x,y) over the y-axis?

• (x,y)→(x,y)

• (x,y)→(-y,x)

• (x,y)→(-x,y)

• (x,y)→(y,x)

What happens to the y-coordinate when a point is reflected over the x-axis?

• It remains the same.

• It changes to its opposite sign.

• It becomes zero.

• It doubles in value.

What is the general rule for reflecting a point (x,y) over the x-axis?

• (x,y)→(x,-y)

• (x,y)→(-x,y)

• (x,y)→(-x,-y)

• (x,y)→(y,x)

If point (3,-4) is reflected over the x-axis, what is the new point?

• (3,-4)

• (-3,-4)

• (3,4)

• (-3,4)

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

• remains the same

• changes to its opposite sign

• becomes zero

• is doubled

Reflect the point (-3,-2) over the y-axis. What is the image point?

• (3,-2)

• (-3,2)

• (3,2)

• (-3,-2)

If point (a,b) is reflected over the x-axis, what is the resulting point?

• (a,b)

• (a,-b)

• (-a,b)

• (-a,-b)

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

• (-2,7)

• (2,7)

• (-7,2)

• (7,-2)
