The number of solutions for the coincident lines is infinity many solutions.
What is the linear system?
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A coordinate plane is shown with two lines graphs.
Line M has a slope of 1 and passes through the y axis at negative 2.
Line N has a slope of 1 and passes through the y axis at negative 2.
It means that both lines are one over the other which is coincident.
Then the number of solutions for the coincident lines is infinity many solutions.
