Hi, 

Solve the system of equations by graphing. Then classify the item.

 y=-x-8 Pt(0,8) and (-8,0)

9x-8y=-21 Pt (0,21/8) and (-21/9,0)

Plot Pts ,connect with respective lines.

Lines Intersect at Pt(5,-3) system is Independent



A consistent system has at least one solution.

An inconsistent system has no solutions.

An independent system has exactly one solution. ****

A dependent system has infinitely many solutions.
