<u>Given</u>:
Given that the two linear equations in the graph are and
We need to determine the number of solutions can be determined from the system of linear equations.
<u>Solutions:</u>
The number of solutions to the system of linear equations can be determined using the substitution method.
Substituting in the equation
, we get;
Subtracting both sides of the equation by 2x, we get;
Subtracting both sides of the equation by 6, we have;
Dividing both sides of the equation by -5, we get;
Thus, the value of x is 2.
Substituting in the equation
, we get;
Thus, the value of y is 0.
Hence, the solution to the system of linear equations is (2,0)
Therefore, the system of equations have one solution.
Thus, Option B is the correct answer.
