A number line can visually represent the solutions of an inequality by marking the relevant points and shading the appropriate region. For example, if the inequality is ( x > 3 ), you would place an open circle at 3 (indicating that 3 is not included) and shade to the right to show all numbers greater than 3. Conversely, for ( x \leq 2 ), you would place a closed circle at 2 and shade to the left to indicate all numbers less than or equal to 2. This method provides a clear visual representation of the solution set.

Which is true of the infinite solutions of the inequality X0?
The statement "X0" is unclear, but if you are referring to an inequality such as x > 0 or x ≤ 0, it indicates that there are infinite solutions within the specified range. For instance, if the inequality is x > 0, the solutions include all positive real numbers. These solutions can be represented on a number line or in interval notation, such as (0, ∞) for x > 0.
What is the points where used to graph linear inequalities?
To graph linear inequalities, you first identify the boundary line by rewriting the inequality in slope-intercept form (y = mx + b) and plotting the corresponding linear equation. If the inequality is strict (e.g., < or >), you use a dashed line to indicate that points on the line are not included. For non-strict inequalities (e.g., ≤ or ≥), a solid line is used. Finally, you shade the appropriate region of the graph to represent the solutions that satisfy the inequality, based on whether the inequality is greater than or less than.
What does the open dot on a number line mean?
An open dot on a number line indicates that the point it represents is not included in the set of values being considered. This typically signifies a strict inequality, such as "<" or ">", meaning that the number at that point is excluded from the solution. For example, if the inequality is x < 3, the open dot at 3 shows that 3 itself is not part of the solutions.
Can a pair of linear equation have exactly two solutions?
No. A pair of linear equation can have 0 solutions (they are parallel), or one solution (they cross at one point) or an infinite number of solutions (they represent the same line).

What does a dashed line represent on a graph?
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.
Write an inequality for each sentence Graph the solutions of each inequality on a number line r is not greater than five?
r <= 5.
Why is graphing the solutions of an inequality is more efficient than listing all the solutions of the inequality?
because writing out all the solutions is not necessarliy a correct answer but a number line is and because graphing out also helps you get a mental image of the concept.
Which compound inequality is graphed on the number line?
Any compound inequality, in one variable, can be graphed on the number line.
Why do we represent the solution to an inequality with a graph on a number line but we don't do the same for the solution to an equation?
An equation has an equal sign, which means that we know what the variable is equal to :)
In the graph of a linear inequality the shaded region above or below the line is called?
The shaded region above or below the line in the graph of a linear inequality is called the solution region. This region represents all the possible values that satisfy the inequality. Points within the shaded region are solutions to the inequality, while points outside the shaded region are not solutions.
What does the open dot on a number line mean?
An open dot on a number line indicates that the point it represents is not included in the set of values being considered. This typically signifies a strict inequality, such as "<" or ">", meaning that the number at that point is excluded from the solution. For example, if the inequality is x < 3, the open dot at 3 shows that 3 itself is not part of the solutions.
When graphing inequalities where can solutions be found?
I think that you are asking about the linear inequalities with two variables, so my answer is related to them. First, you have to draw the boundary line (be careful, if your inequality does not contain the equal sign, the boundary line will be a dashed line, because the points on the line are not solutions to the inequality), which divide the coordinate system in two half-planes. Second, you have to test a point on either sides of the line (the best point is the origin, (0, 0), if it is not on the boundary line). If that point satisfies the inequality, then there are all its solutions, otherwise they are to the opposite side.
Can a pair of linear equation have exactly two solutions?
No. A pair of linear equation can have 0 solutions (they are parallel), or one solution (they cross at one point) or an infinite number of solutions (they represent the same line).
Why is a linear equation shaded?
Actually, a linear inequality, such as y > 2x - 1, -3x + 2y < 9, or y > 2 is shaded, not a linear equation.The shaded region on the graph implies that any number in the shaded region is a solution to the inequality. For example when graphing y > 2, all values greater than 2 are solutions to the inequality; therefore, the area above the broken line at y>2 is shaded. Note that when graphing ">" or "=" or "
What does the graph of a line represent?
It represents all solutions to the linear equation.
