Question

1. triangle ijk has the coordinates listed: i(5, -8) j(10, -8) k(7, -4) where is j after a reflection over the y - axis?

Explanation:

Step1: Recall reflection rule

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

Step2: Apply rule to point J

Point J has coordinates $(10, - 8)$. Using the rule $(-x,y)$, we get $(-10,-8)$.

Answer:

(-10,-8)
