Question

graph the image of f(-1, 9) after a reflection over the y - axis.

Explanation:

Step1: Recall reflection rule

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

Step2: Apply the rule

Given the point $F(-1,9)$, when we apply the rule, we change the sign of the $x -$coordinate. So, $x=-1$ becomes $x = 1$ and $y = 9$ remains the same. The new point is $(1,9)$.

Answer:

The image of the point $F(-1,9)$ after reflection over the $y -$axis is $(1,9)$. To graph it, locate the point where $x = 1$ and $y=9$ on the given coordinate - grid.
