Please look in your text book for this problem Statement

Graph each inequality. The intersection of graphs forms a triangle.   system of inequalities y lessthanorequalto x and y greaterthanorequalto -3 and 3y+5x lessthanorequalto 16 graph

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 .


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 .
