Question

b. here are some points. what are the coordinates of d, e, and f after a reflection over the y - axis? plot these points on the grid, and label them d, e and f.

Explanation:

Step1: Recall reflection rule

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

Step2: Find coordinates of $D'$

Given $D(-2,3)$. Using the rule, $x=-2,y = 3$, so $D'=(2,3)$.

Step3: Find coordinates of $E'$

Given $E(-4,0)$. Using the rule, $x=-4,y = 0$, so $E'=(4,0)$.

Step4: Find coordinates of $F'$

Given $F(2,-2)$. Using the rule, $x = 2,y=-2$, so $F'=(-2,-2)$.

Answer:

$D'(2,3), E'(4,0), F'(-2,-2)$
