Answer

A system of linear equations having infinitely many solutions when plotted on a graph shows both equations overlapping on one another.

Work Step by Step

A system of linear equations can have exactly one solution, no solution, or infinitely many solutions. A system of equations is said to be having infinitely many solutions when we encounter a true statement while solving the equations using the addition or substitution method. A system of linear equations having infinitely many solutions when plotted on a graph shows both equations overlapping on one another.
