**Q.1.** Which one of the following options is true, and why? y = 3x + 5 has

(i) a unique solution, (ii) only two solutions, (iii) infinitely many solutions

**Solution:**

** **Any linear equation will have (iii) infinitely many solutions. For each value of x, we will get a value of y. Since there is no limit to taking the values of x, we will have infinite number of solutions.
