Option 1 - There is one solution : (0,-1)

Step-by-step explanation:

Given : The system of equations and

To find : How many solutions does this linear system have?

Solution :

Let Equation (1),

Equation (2),

Applying substitution method,

Substitute y from equation (1) into (2),    Substitute in equation (1),  Therefore, There is one solution : (0,-1)

So, Option 1 is correct.
