Draw a horizontal line, mark integers every unit, add tick marks for halves, quarters. Plot 1, 3.25, -2, 2.5.
Creating a number line involves representing numbers on a straight line, with integers usually marked as tick marks. Let's create a number line with the given points: 1, 3.25, the opposite of 2, and –(–4/2).
Start with a blank number line:
Draw a straight line horizontally across the paper.
Label the endpoints with arrows to indicate that the line extends indefinitely.
Mark the integers:
Place integers along the line with equal spacing. A common convention is to label integers at regular intervals, such as every inch or centimeter.
Assume you're marking integers from left to right: ..., -3, -2, -1, 0, 1, 2, 3, ...
Plot the given points:
Point 1: Locate the integer 1 on the number line. Plot a point directly above it.
Point 3.25: Find the space between integers 3 and 4. Divide this space into quarters. Mark 3.25 in the appropriate location.
Opposite of 2: The opposite of 2 is -2. Locate -2 on the number line and plot a point above it.
–(–4/2): Simplify –(–4/2) to 4/2, which is 2. Locate 2 on the number line and plot a point above it.
Tick marks:
Add tick marks between each pair of integers to represent values between whole numbers. The number of tick marks between integers depends on the scale you choose for your number line. Common choices are dividing each space into halves or quarters.
Label tick marks:
If you've divided each space into halves or quarters, label the tick marks accordingly. For example, between 1 and 2, you might have tick marks labeled 1.5.
Question
Describe in detail how you would create a number line with the following points: 1, 3.25, the opposite of 2, and – (–4fraction of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer.
