Point C (2, 3) does not lie on the line and does not satisfy the equation, since 3(2) – 7(3) = -15 ≠ 21. Points not on the line can never satisfy the equation.

Class 9 Ganita Manjari Part 2 Chapter 13 Page 93 Question Answer
Point C (2, 3) clearly does not lie on the graphed line. Substituting x = 2 and y = 3 gives LHS = 3(2) – 7(3) = 6 – 21 = -15, which does not equal 21 (RHS). Therefore, it does not satisfy the equation. Geometrically, every solution corresponds strictly to a point on the line; hence, points not lying on the line cannot satisfy the equation.
