When graphing inequalities you use a circle to indicate a value on a graph. If the value is included in the solution to the inequality you would fill in the circle. If the value that the circle represents is not included in the solution you would leave the circle unshaded.

How do you know weather to shade above or below the line when graphing an inequality on the coordinate plane?

If the inequality has a > or ≥ sign, you shade above the line. If the inequality has a < or ≤ sign, you shade below it. Obviously, just an = is an equation, not an inequality.


How is graphing a linear inequality the same as graphing a liner equation?

They are alike in that you graph the lines in the same way, but they are different because you have to shade in one side of the line


How is graphing a linear inequality different than graphing a linear equation?

In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it


How do you find the equation of a line without graphing?

There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line. Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula, Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,


When graphing a linear inequality when can you NOT use (0 0) as a test point to determine which side of a boundary line to shade?

When the line goes through the origin like y>3x. Notice that there is no constant added to the end.


What is the difference between graphing a line and graphing an inequality?

when graphing a line you simply plot the points based on the ordered pairs and connect the dots; there you have a line. An inequality graph refers to the shaded region of the coordinate plane that does not coincide with the line, hence the term, inequality.


When graphing an inequality with the symbol less than or equal to what is drawn?

if you have y <= f(x), then graph the function y = f(x) with a solid line, then shade everything below that graph.


How do you know where to shade on a graph?

If you mean with inequalities: 1. Change the inequality into an equation.2. Solve the equation for the initial line.3. Look back to the inequality.a.) greater than or equal to-shade above or to the left of your line,this line should be solidb.) greater than-shade above or to the left of your line,this line should not be solidc.) less than or equal to-shade below or to the right of your line,this line should be solidd.) less than-shade below or to the right of your line,this line should not be solidHope this helps.

How is graphing an inequality different from graphing a line on a coordinate plane?

Whereas the procedure for a linear equality is the same, the inequality defines all of the plane on one side (or the other) of the corresponding line.


When you graph inequalities how do you know what to shade?

Pick a test point, (the origin is the most convenient unless the line of the inequality falls on it), and plug it into the same linear inequality. If the test point makes the inequality true, then shade that side of the line. If the test point makes the inequality false, then shade the opposite side of the line.
