What will be obtained if the line 2x + y = 8 is drawn twice separately?

Answer and explanation

Correct answer: The same line

A straight line is determined by its equation. Drawing 2x + y = 8 a second time does not change any coefficient or constant, so the second graph has exactly the same set of points as the first graph. The two representations therefore coincide and appear as one line, although algebraically they have been drawn twice. Every point on this line is common to both equations, which corresponds to infinitely many common solutions. Hence option C is correct. Option A would require parallel but distinct equations, option B is not possible because two lines cannot have two separate intersections, and option D is false because the equation does produce a valid graph.
