For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. For and >, use an open circle to indicate the number itself is not part of the solution.

This step-by-step guide on graphing linear inequalities will show you how to graph a linear inequality on the coordinate plane. The guide will review when to use a solid or dotted line as …

Strict inequalities without the “or equal to” component are indicated with an open dot on the number line and a parenthesis using interval notation. Compound inequalities that make use of …

A closed (solid) dot indicates that the endpoint is included in the curve, while an open dot indicates that it is not. It’s similar to the distinction between “less than or equal to” and “less …

To draw the graph, place an open dot on the number line first, and then draw a line extending to the left. Draw an arrow at the leftmost point of the line to indicate that it continues for infinity.

When you're doing a graph of a solution, the square bracket notation goes with the parenthesis notation, and the closed (that is, the filled in) dot notation goes with the open dot notation.

A solid dot on a number line graph indicates that the given number should be included as a possible solution, whereas an open dot indicates that the given number cannot be a solution. …

We use the open and closed dots to make this distinction. I put a closed dot at the "5" end of the interval to indicate that x = 5 satisfies the inequality, and I put an open dot at the "1" end of the …

We can graph inequalities with one variable on a number line. We use a closed dot, \bullet, ∙, to represent \leq ≤ and \geq. ≥. We use an open dot, \circ, ∘, to represent << and >.>. If x \geq -1, …

Ex: x < 4 is read “x is less than 4” and the graph: Ex: 4 > x is read “x is less than 4” You can rewrite the inequality so that the variable is always on the left.
