Question
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
The true option is (iii) y = 3x + 5 has infinitely many solutions.
Reason. For every value of x, there is a corresponding value of y and vice-versa.
