## What is the inequality for x 0?

On a number line graph, we would start with an open circle on 0, because 0 IS NOT included in the solution. Draw a line extending to the left, indicating that x can be any value to the left of 0. On ax-y- grid, we would have a vertical line to represent x = 0, but as 0 IS NOT included, the line would be dotted.

## How do you know when to shade a graph in inequalities?

Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line. For a vertical line, larger solutions are to the right and smaller solutions are to the left.

**Which quadrants x 0 y 0 Will the inequalities shade?**

the solution set is everything in the upper right quadrant of the Cartesian plane including the positive x and y axes (and the point (0,0) .

### What are the rules of inequalities?

Rules for Solving Inequalities

- Add the same number on both sides.
- From both sides, subtract the same number.
- By the same positive number, multiply both sides.
- By the same positive number, divide both sides.
- Multiply the same negative number on both sides and reverse the sign.

### How do you graph inequalities step by step?

Steps on Graphing Linear Inequalities

- Step 1: Always start by isolating the variable y on the left side of the inequality.
- Step 2: Change the inequality to equality symbol.
- Step 3: Graph the boundary line from step 2 in the X Y − XY- XY−plane.
- Step 4: The last step is to shade one side or region of the boundary line.

**How do you represent inequalities on a graph?**

How to Graph a Linear Inequality

- Rearrange the equation so “y” is on the left and everything else on the right.
- Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).

#### What does Y 0 look like on a graph?

To review, there are two methods you can use to graph y=0: the slope intercept form and plugging in values. But you can also remember a shortcut, which is that a slope of zero will always be represented as a horizontal line and therefore, when y=0, the graph will essentially show a line through the x-axis.

#### What is X 0 called?

x-intercept

Take a closer look, and you’ll see that the y-axis is also the line “x = 0”. In the same way, the x-axis is also the line “y = 0”. Then, algebraically, an x-intercept is a point on the graph where y is zero, and.

**How does 0 look like on a graph?**

Lesson Summary But you can also remember a shortcut, which is that a slope of zero will always be represented as a horizontal line and therefore, when y=0, the graph will essentially show a line through the x-axis.

## How to graph the inequalities x ≥ 0 and y ≥ 0?

How would I graph the inequalities x ≥ 0 and y ≥ 0? the solution set is everything in the upper right quadrant of the Cartesian plane including the positive x and y axes (and the point (0,0).

## Which is the correct way to shade a graph?

Since 0 is greater than -6, we will shade above the line that since it contains (0,0). Step 4: Shade your graph. Step 5: Identify three points that are solutions to the inequality. This means that you can pick any three points that are in the shaded area.

**When to use dotted line or solid line in graphing inequalities?**

If the inequality symbol is greater than or less than, then you will use a dotted boundary line. This means that the solutions are NOT included on the boundary line. If the inequality symbol is greater than or equal to or less than or equal to, then you will use a solid line to indicate that the solutions are included on the boundary line.

### Which is the first step in graphing linear inequalities?

There will be two additional steps that you must take when graphing linear inequalities. As shown in this image, the first step will be to determine whether you will use a solid boundary line or a dashed boundary line. The inequality symbol will help you to determine the boundary line.
