Question

1 multiple choice 2 points the diagram shows triangle abc. which set of coordinates defines the reflection of triangle abc over the y - axis? {(-2,2), (-3,-2), (-1,-1)} {(-2,2), (-1,-2), (-3,-1)} {(2,-2), (3,2), (1,1)}

Explanation:

Step1: Identify original coordinates

From the graph, assume $A(2, 2)$, $B(3,-2)$, $C(1,-1)$.

Step2: Apply reflection rule

The rule for reflecting a point $(x,y)$ over the $y -$axis is $(-x,y)$.
For point $A(2,2)$, its reflection is $(-2,2)$.
For point $B(3,-2)$, its reflection is $(-3,-2)$.
For point $C(1,-1)$, its reflection is $(-1,-1)$.

Answer:

{(-2,2), (-3,-2), (-1,-1)}
