What's the function of the boundary line?
-
It acts as the boundary of the Y-axis only
-
It divides the plane into half planes
-
It's the first answer after calculating the axes
-
There's nothing like boundary line
Correct Answer
A. It divides the plane into half planesExplanation
The boundary line in a plane divides it into half planes. This means that any point on one side of the boundary line will satisfy a certain inequality, while any point on the other side will satisfy the opposite inequality. Therefore, the boundary line plays a crucial role in defining and separating different regions or areas in the plane.Rate this question:

How many points (i.e 2,0,5) does two axes need in inequalities?
-
3.5
-
1
-
3
-
2
Correct Answer
A. 2Explanation
Two axes are needed in inequalities because inequalities involve two variables. Each axis represents one variable, so two axes are required to graph the relationship between the two variables. This allows us to visually represent the solution set of the inequality and determine the points that satisfy the inequality. Therefore, the correct answer is 2.Rate this question:

What does “Greater Than” change to when you divide through by negative (minus)?
-
Less than
-
Remains greater than
-
Less than or equal to
-
Equal to
Correct Answer
A. Less thanExplanation
When you divide through by a negative number, the inequality sign changes direction. In this case, "Greater Than" changes to "Less than" because when you divide by a negative number, the inequality flips. For example, if we have 5 > -10 and we divide both sides by -1, it becomes -5 < 10. Thus, the correct answer is "Less than."Rate this question:

Which point is shaded on the graph?
-
Opposite of the solution area
-
Solution area
-
No area
-
The Y-axis
Correct Answer
A. Solution areaExplanation
The correct answer is "Solution area." This means that the shaded point on the graph represents the area where the solution lies. In other words, it indicates the values or points that satisfy the given problem or equation.Rate this question:

How many axis/axes do you need at the basic level?
-
5
-
1
-
2
-
4
Correct Answer
A. 2Explanation
At the basic level, you need two axes. Axes refer to the imaginary lines that are used to define the position and movement of objects in space. In a two-dimensional coordinate system, there are two axes - the x-axis and the y-axis. These axes intersect at a point called the origin and are used to locate points on a plane. Therefore, at the basic level, two axes are required to describe the position and movement of objects.Rate this question:

Do you think degrees are utilized when calculating inequalities at the lowest level?
-
Up to 360 degrees
-
Capped off at 180 degrees
-
None
-
Only when calculating the intersection box
Correct Answer
A. NoneExplanation
Degrees are not utilized when calculating inequalities at the lowest level. Inequalities involve comparing two values or expressions using symbols such as greater than (>), less than (Rate this question:

Why is the solution area shaded?
-
I chose there's no shaded area already
-
To indicate that it's useless
-
To clearly identify which part is the solution
-
Aesthetic appeal only
Correct Answer
A. To clearly identify which part is the solutionExplanation
The solution area is shaded to clearly identify which part is the solution. By shading the solution area, it becomes visually distinct from the rest of the diagram or graph, making it easier for the viewer to identify and understand where the solution lies. This shading helps to highlight the relevant information and guide the reader's attention towards the intended solution.Rate this question:
