When you have either of these symbols ≤, or ≥ in a linear equation, what kind of line do you use to graph the equation?

Step-by-step explanation:

If you have those, it is not an equation. It is an inequality and you must shade above or below the line, depending on whether the points in the shaded region make the inequality true or not. Your line will be the border. This, you must treat as a linear equation, so remove the inequality for an equal sign and draw the line. If there is a line underneath the inequality, it means equal to, so your line is completely solid. If there is no line and it is just < or > that means that the line is dashed.
