Question

What is the reflected image in the x-axis A(- 1, 8), B(- 8, 8) C(- 5, 1) ?

Answer 1

`A' = (- 1, -8)`

`B' = (-8, -8)`

`C' = (-5, -1)`

Explanation:

Given

`A = (- 1, 8)`

`B = (-8, 8)`

`C = (-5, 1)`

Required

Determine the reflected image in the x axis

When a point is reflected across the x axis, the x coordinate remains the same, while the y coordinate is negated.

In other words,

`A(x,y)` when reflected becomes
`A'(x,-y)`

So, for each of the following points

`A = (- 1, 8)`

`B = (-8, 8)`

`C = (-5, 1)`

There images are:

`A' = (- 1, -8)`

`B' = (-8, -8)`

`C' = (-5, -1)`
