Line 2x + y = 6 passes through (0, 6) and (3, 0). Line 2x − y = 2 passes through (0, −2) and (1, 0). Plotted on a graph, both lines intersect at (2, 2).

Class 9 Maths Ganita Manjari Part 2 chapter 13 Two Variables, One Line solutions
Plot the first equation 2x + y = 6 using the points (0, 6) and (3, 0). Next, express the second equation as y = 2x − 2 and plot using points (0, −2) and (1, 0). Drawing straight lines through these pairs on a coordinate grid reveals that they intersect at the unique point (2, 2), giving the solution x = 2, y = 2.
