Without graphing, classify each system of equations as independent, dependent, or inconsistent. Solve independent systems by graphing.
{1+ y = I
{1 =+y =1
The first equation is written incorrectly. However, assuming you meant:
1 + y = I
1 = y + 1
1 + y = I can be rewritten as y = I - 1.
1 = y + 1 can be rewritten as y = 1 - 1.
For the second equation, y = 1 - 1 simplifies to y = 0.
Therefore, the system of equations becomes:
y = I - 1
y = 0
This is a dependent system of equations, as both equations represent the same line. The solution is all points on the line y = 0.
