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 <i>consistent</i> system has at least one solution.
An <i>inconsistent</i> system has no solutions.
An <i>independent</i> system has exactly one solution. ****
A <i>dependent</i> system has infinitely many solutions.
