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.

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

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

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

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.

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

Line Graph, and I know that these are Study Island questions.

Shade to the left of the point on the number line.

In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.

yes, and the x-axis is horizontal

If it is <= or >=

strict inequality

By substitution

The imaginary line that circles the earth is the Equator.

The line that includes whatever variables are included in the equation.

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.

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.

The first is 2-dimensional, the second is 1-dimensional.

The imaginary line that circles the middle of the earth is called the equator.
