Question

you just reflected points a, b, and c over the y - axis. now, record the coordinates of points a, b, and c, the images of points a, b, and c after this reflection.
a (7,8) b (-6,3) c (-3,-7)

Explanation:

Step1: Recall reflection rule

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

Step2: Find coordinates of $A'$

For point $A(7,8)$, applying the rule $(-x,y)$, we get $A'(-7,8)$.

Step3: Find coordinates of $B'$

For point $B(-6,3)$, applying the rule $(-x,y)$, we get $B'(6,3)$.

Step4: Find coordinates of $C'$

For point $C(-3,-7)$, applying the rule $(-x,y)$, we get $C'(3,-7)$.

Answer:

$A'(-7,8)$, $B'(6,3)$, $C'(3,-7)$
