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)

we should prevent inequality by
point
The shaded area of the graph of an inequality show the solution to the inequality. For example, if the area below y = x is shaded it is showing those ordered pairs which solve y < x.
Very Carefully :)
