To locate the intersection of the graphs of the two equations, plot the point (3,9) on the coordinate grid.
The solution to a system of two linear equations represents the point where the two lines intersect on the coordinate plane.
Yes, a linear system of equations can have infinitely many solutions if the two equations represent the same line.
No, a linear system of equations can either have one unique solution, infinitely many solutions, or no solutions at all.
Yes, a linear system of equations can have no solutions if the two lines are parallel and never intersect on the coordinate plane.
