Explanation:

Step1: Recall reflection rule

For a point $(x,y)$ reflected over the line $y = k$, the new - $y$ value is $y'=2k - y$ and the $x$ - value remains the same. Here $k=-1$.

Step2: Let's assume a point $(x,y)$ on the original figure

The reflected point $(x',y')$ has $x' = x$ and $y'=2\times(-1)-y=-2 - y$. For example, if we have a point $(x_1,y_1)$ on the original triangle, its reflected point will be $(x_1,-2 - y_1)$. We repeat this process for all the vertices of the triangle in the figure.

Answer:

To plot the reflected figure, for each vertex $(x,y)$ of the original figure, find the new vertex $(x,-2 - y)$ and plot these new points. Then connect the new points to form the reflected figure.
