Question

The equation $y=2x+3$ has

• A. Unique solution
• B. No solution
• C. Only two solutions
• D. Infinitely many solutions

Answer 1

The correct option is D Infinitely many solutions

As can be seen, the line for $y=2x+3$ extends up to infinity all over the number line.

For $x=0,y=3$, For $x=1,y=5$, For $x=2,y=7$

$\therefore$ For every value of $x$ we get the different value of $y$

Hence it will have infinitely many solutions.
