Example 5 Graphically, find whether the following pair of equations has no solution, unique solution or infinitely many solutions: 5x– 8y+ 1 = 0 & 3x – 24/5y + 3/5 = 0 5x − 8y + 1 = 0 3x – 24/5 y + 3/5 = 0 Solving (1) 5x − 8y + 1 = 0 8y = 5x + 1 y = (5𝑥 + 1)/8 Solving (2) 3x − 24/5 y + 3/5 = 0 24/5 y = 3x + 3/5 24/5 𝑦 = (3𝑥 × (5)+ 3)/5 24𝑦 = 15𝑥 + 3 y = (15𝑥 + 3)/24
