question

Graph the image of

(

–

)

after a reflection over the

y-axis.

key idea

A reflection flips a figure over a line to create a mirror image.

When a point is reflected over the

y-axis,

the

x-coordinate

changes sign.

solution

Start with the point

(

–

)

and the

y-axis.

Find the mirror image of the point on the other side of the line. Since

is 1 unit to the left of the

y-axis,

is 1 unit to the right of the

y-axis.

The image is
