Graph each inequality. The intersection of graphs forms a triangle.  

The coordinates (2, 2) and (3, 3) can be determinate from the graph.

To find the third vertex, solve the system of equations and .

Substitute in .

The third vertex is .

Check:

Compare the coordinates to the coordinates on the graph.

The x- coordinate of the third vertex is at 5.

The y- coordinate of the third vertex is at 3.

The vertices of a triangle are at .
