Question

reflect across the y - axis. (be sure to label the new image points and draw the new image)

Explanation:

Step1: Recall reflection rule

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

Step2: Assume coordinates

Let's assume the coordinates of point $C$ are $(x_1,y_1)$, of point $K$ are $(x_2,y_2)$ and of point $W$ are $(x_3,y_3)$.

Step3: Find new - coordinates

The new coordinates of $C$ after reflection across the $y - axis$ will be $C'(-x_1,y_1)$, of $K$ will be $K'(-x_2,y_2)$ and of $W$ will be $W'(-x_3,y_3)$.

Step4: Plot new points

Plot the points $C'$, $K'$ and $W'$ on the coordinate - plane and connect them to form the reflected triangle.

Since we don't have the actual coordinates from the image, the general method for reflection across the $y - axis$ is as described above. If we assume for example $C(-3,1)$, $K(-2,4)$ and $W(1, - 1)$:

Step5: Calculate new coordinates (example)

For $C(-3,1)$, the reflected point $C'(3,1)$; for $K(-2,4)$, the reflected point $K'(2,4)$; for $W(1,-1)$, the reflected point $W'(-1,-1)$. Then plot these new points and draw the new triangle.

Answer:

Follow the steps above to reflect the triangle across the $y - axis$, label the new points (e.g., if the original points are $C$, $K$, $W$, the new points are $C'$, $K'$, $W'$) and draw the new triangle.
