Question

Triangle xyz is reflected across the x-axis, and x = (–11, 8). what are the coordinates of x’ ?

Answer 1

Hence the reflection of the point x=(-11,8) across the x-axis is given by:

x'=(-11,-8).

Explanation:

We are given a triangle xyz such that this triangle xyz is reflected across the x-axis.

Also the coordinates of the point x of the triangle xyz is given as:

x=(-11,8)

We know that reflection of any point (a,b) across the x-axis is given by

(a,-b).

So after the reflection of triangle xyz across the x-axis the point x is translated to x'.

Hence the reflection of the point x=(-11,8) across the x-axis is given by:

x'=(-11,-8).

Answer 2

Coordinates of x´ are ( - 11 , - 8 ).
