Question

The Equation $y=2x+3$ has

Answer 1

The line $y=2x+3$ extends up to infinity all over the number line.

$$\begin{gathered} Forx=0,y=3. \\ Forx=1,y=5. \\ Forx=2,y=7. \end{gathered}$$

Therefore, for every value of $x$, we get a different value of $y$.

Similarly, we can find infinitely many solutions for this line

Hence, the given equation has infinitely many solutions.
