Question

What type of transformation transforms (a, b) to ​(−a, b)​?

a reflection over the y-axis

a translation of 1 unit up

a reflection over the x-axis(i tink its this one)

a translation of 1 unit down

Answer 1

hello :
a reflection over the y-axis

Answer 2

Option A is correct

a reflection over the y-axis

Explanation:

The rule of reflection over y-axis is given by:

`(x, y) \rightarrow (-x, y)`

As per the statement:

Given the transform,

(a, b) to (-a, b)

By definition of reflection;

The given transform is, a reflection over the y-axis

Therefore, a transformation is, a reflection over the y-axis
