Question

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

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 $C(x_1,y_1)$, $K(x_2,y_2)$ and $W(x_3,y_3)$ are the coordinates of the vertices of the triangle. Their reflected points $C'( - x_1,y_1)$, $K'( - x_2,y_2)$ and $W'( - x_3,y_3)$ across the $y$-axis.

Step3: Plot new points

On the coordinate - grid, plot the points $C'$, $K'$ and $W'$ and connect them to form the new triangle.

Answer:

Plot the points obtained by changing the sign of the $x$-coordinates of the original points and connect them to get the reflected triangle.
