The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>).
If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.

It can represent the graph of a strict inequality where the inequality is satisfied by the area on one side of the dashed line and not on the other. Points on the line do not satisfy the inequality.
An equation has an equal sign, which means that we know what the variable is equal to :)
If it is a straight line, then the equation is linear.

The graph of an inequality is a region, not a line.

If the points that are ON the line satisfy the inequality then the line should be solid. Otherwise it should be dotted. Another way of putting that is, if the inequality is given in terms of ≤ or ≥, then use a solid line. If they are < or > use a dotted line.
The graph will be a line.
y -x - 2 is not an equation (nor an inequality) and so there is no way to graph it.
First, write the equation of the line of the graph. Next, if the line is solid, it means equal to. If it is dotted: not equal to. Lastly, the shaded portion of a graph is where the points satisfy the equation. So pick a point in the shaded region, plug it in, and put the appropriate larger than, or less than sign to make the statement true. EX: plug in (3,1) to y _ 3x+1 1 _ 10, then 1 < 10 So, y < 3x + 1 (add [or equal to] if the line is solid)
When it is a linear equation.
If it is a 'greater than' or a 'less than' then it's a dotted line. If 'less than or equal' or if it's a 'greater than or equal' then it's a solid line.
