Answer:
The coordinate plane with two parallel lines shows a system of equations with no solution.
Explanation:
Two intersecting lines on the coordinate plane have a definite solution.
Two coinciding lines on the coordinate plane have infinitely many solutions as they intersect at infinitely many points.
And, two parallel lines on the coordinate plane has no solution as they never intersect with each other.
Therefore, the coordinate plane with two parallel lines shows a system of equations with no solution. (Answer)
