Question

complete the table to show the coordinates of △abc and its image.
△abc △abc
a(-4,3) ?
b(-2,1) ?
c(-4,1) ?

Explanation:

Step1: Assume reflection over y - axis

For a point $(x,y)$ reflected over y - axis, new point is $(-x,y)$.

Step2: Find $A'$

$A(-4,3)$ becomes $A'(4,3)$.

Step3: Find $B'$

$B(-2,1)$ becomes $B'(2,1)$.

Step4: Find $C'$

$C(-4,1)$ becomes $C'(4,1)$.

Answer:

$A'(4,3)$
$B'(2,1)$
$C'(4,1)$
