The graph below shows the inequality x<3.

Explanation:

enter image source here

All points that lie in the shaded area satisfy the equation x<3.
In other words, x can take any value less than 3.
x!=3 or any number that is greater than 3.

Since there is strict inequality, i.e., x<3, the points that lie on the line x=3 will not satisfy the equation.
Therefore, a dotted line is used to mark x=3.
