What is the solution to the system of linear equations graphed below?
OlgaM077 [116]

Option C: There are no solutions

Explanation:

The linear equations is graphed.

We need to determine the solution of the system of equations.

The solution of the equations can be determined by finding the point of intersection of the two equations.

From the figure, it is obvious that the two equations are parallel to each other.

Also, the parallel lines have the same slope and the parallel lines never intersect.

Hence, the system consisting of parallel lines have no solution.

Therefore, the solution to the system of linear equations graphed is no solution.

Thus, Option C is the correct answer.
