Question

1. plot the following points of △abc. then reflect the triangle across the y - axis. label all 6 of the points with their ordered pair. a(-5,2) b(-4,-5) c(-1,-2)

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ across the y - axis, the rule is $(-x,y)$.

Step2: Reflect point A

Given $A(-5,2)$, applying the rule $(-x,y)$, we get $A'(5,2)$.

Step3: Reflect point B

Given $B(-4,-5)$, applying the rule $(-x,y)$, we get $B'(4,-5)$.

Step4: Reflect point C

Given $C(-1,-2)$, applying the rule $(-x,y)$, we get $C'(1,-2)$.

Answer:

The original points are $A(-5,2)$, $B(-4,-5)$, $C(-1,-2)$. The reflected points across the y - axis are $A'(5,2)$, $B'(4,-5)$, $C'(1,-2)$.
