b
(1, 1) and (0, 0)
c
This system has infinitely many solutions.
d
This system has exactly one solution.

c

This system has infinitely many solutions.

Step-by-step explanation:

Solve by substitution:

1) Solve for :

2) Substitute for in :

3) Simplify both sides of the equation:

Therefore, This system has infinitely many solutions.

Solve by elimination:

You can't solve this system of equations by elimination.

Solve by graphing:

The lines are directly on top of each other, Therefore there are infinitely many solutions.
