Graph integers on horizontal and vertical number lines

Graph integers on horizontal and vertical number lines by Delta publications

key notes :

Understanding Number Lines:
  • Horizontal Number Line: A straight line where numbers increase to the right and decrease to the left.
  • Vertical Number Line: A straight line where numbers increase as you move up and decrease as you move down.
Plotting Integers on a Horizontal Number Line:
  • Draw a horizontal line and mark the center point as 0.
  • To the right of 0, mark positive integers at equal intervals (1, 2, 3, …).
  • To the left of 0, mark negative integers at equal intervals (-1, -2, -3, …).
Plotting Integers on a Vertical Number Line:
  • Draw a vertical line and mark the center point as 0.
  • Above 0, mark positive integers at equal intervals (1, 2, 3, …).
  • Below 0, mark negative integers at equal intervals (-1, -2, -3, …).
Graphing a Single Integer:
  • Locate the integer on the number line.
  • Draw a dot or a point at the corresponding position.
Graphing Multiple Integers:
  • Repeat the process for each integer, ensuring each point is accurately placed.
Using the Number Line for Comparison:
  • On a horizontal number line, integers to the right are greater.
  • On a vertical number line, integers above are greater.

Practice Exercises

Plot These Integers on a Horizontal Number Line:

-5, -2, 0, 1, 4

Plot These Integers on a Vertical Number Line:

3, 0, -1, -3

Answer the Questions:

  1. Which is farther from 0: -6 or 5?
  2. On a thermometer, if the temperature changes from -2°C to 3°C, how many degrees did it rise?

Learn with an example

🔥Graph 5 and –5 on the number line.

  • Find 5 and –5 on the number line. 5 is positive, so it is to the right of 0. –5 is negative, so it is to the left of 0.Graph the points.
  • Notice that 5 and –5 are the same distance from 0. This means they are opposite numbers.

🗼 Graph –3 and –5 on the number line

  • Find -3 and -5 on the number line. -3 and -5 are negative, so they are to the left of 0.
  • Graph the points
