Ex 4.2, 1 - Which one of following options is true and - Graph of linear equations

  1. Chapter 4 Class 9 Linear Equations in Two Variables (Term 1)
  2. Serial order wise


Ex 4.2, 1 Which one of the following options is true, and why? y = 3x + 5 has a unique solution, (ii) only two solutions, (iii) infinitely many solutions It can be seen that x can have infinite values and for infinite values of x,there can be infinite y So,y = 3x + 5 has infinite possible solutions Hence, the correct answer is (iii).
