$\"\"$

\

Observe the graph:

\

Consider the scale on the $\"\"$ and $\"\"$ -axis is $\"\"$ .

\

Vertices of $\"\"$ are $\"\"$ and $\"\"$ .

\

Translate $\"\"$ units left and up $\"\"$ units.

\

Write the vertex matrix for triangle is $\"\"$ .

\

To translate the triangle $\"\"$ units to the left, add $\"\"$ to each $\"\"$ -coordinate.

\

To translate the figure $\"\"$ units down, add $\"\"$ to each $\"\"$ -coordinate.

\

Adding the translation matrix $\"\"$ .

\

$\"\"$ .

\

Write the vertices of the image.

\

The first row represents the $\"\"$ –coordinates and the second row represents the $\"\"$ –coordinates.

\

The vertices are $\"\"$ and $\"\"$ .

\

$\"\"$

\

The image vertices are $\"\"$ and $\"\"$ .
