In this quiz, we test our understanding of plotting points on a number line.
Try to answer the questions before checking the answers at the bottom of the page.
Instructions
Remember:
A number line is \(1D\).
In \(1D\), each point needs only one value.
Positive numbers are usually plotted to the right of \(0\).
Negative numbers are usually plotted to the left of \(0\).
Questions
Question 1
What does \(1D\) mean?
A) One-dimensional
B) Two-dimensional
C) Three-dimensional
D) Four-dimensional
Question 2
How many values do we need to locate a point in \(1D\)?
A) One value
B) Two values
C) Three values
D) Four values
Question 3
Which of these is an example of a \(1D\) space?
A) A square
B) A cube
C) A number line
D) A sphere
Question 4
Where is the point \(P = 4\) plotted?
A) 4 units to the left of \(0\)
B) 4 units to the right of \(0\)
C) halfway between \(0\) and \(1\)
D) at the origin
Question 5
Where is the point \(P = −5\) plotted?
A) 5 units to the right of \(0\)
B) 5 units to the left of \(0\)
C) halfway between \(0\) and \(1\)
D) at \(0\)
Question 6
Where is the point \(P = 0\) plotted?
A) To the right of \(0\)
B) To the left of \(0\)
C) At the origin
D) Between \(1\) and \(2\)
Question 7
Where is the point \(P = \frac{1}{2}\) plotted?
A) Halfway between \(0\) and \(1\)
B) Halfway between \(1\) and \(2\)
C) Halfway between \(0\) and \(−1\)
D) At \(2\)
Question 8
Where is the point \(P = −\frac{1}{2}\) plotted?
A) Halfway between \(0\) and \(1\)
B) Halfway between \(0\) and \(−1\)
C) At \(−2\)
D) At \(1\)
Question 9
Where is the point \(P = 1.5\) plotted?
A) Between \(0\) and \(1\)
B) Between \(1\) and \(2\)
C) Between \(−1\) and \(−2\)
D) At \(0\)
Question 10
Which statement is correct?
A) A point in \(1D\) needs two values.
B) A point in \(1D\) needs three values.
C) A point in \(1D\) needs only one value.
D) A point in \(1D\) cannot be plotted.
