Distance on Number Line

Front

What is the distance between two points on a number line?

Back

The distance between two points on a number line is the absolute value of the difference between the two numbers.

Front

How do you calculate the distance between -7 and 9 on a number line?

Back

Distance = |9 - (-7)| = |9 + 7| = |16| = 16 units.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, |-5| = 5.

Front

If the temperature is -23 degrees and rises by 5 degrees, what is the new temperature?

Back

New temperature = -23 + 5 = -18 degrees.

Front

What is the final temperature if it rises another 11 degrees from -18 degrees?

Back

Final temperature = -18 + 11 = -7 degrees.

Front

What is the distance from -15 to 15 on a number line?

Back

Distance = |15 - (-15)| = |15 + 15| = |30| = 30 units.

Front

How do you find the distance between -2 and 6?

Back

Distance = |6 - (-2)| = |6 + 2| = |8| = 8 units.

Front

What is the distance between -3 and 30?

Back

Distance = |30 - (-3)| = |30 + 3| = |33| = 33 units.

Front

If the temperature is -3 degrees, how much does it need to rise to reach 30 degrees?

Back

It needs to rise by 30 - (-3) = 30 + 3 = 33 degrees.

Front

What is the distance between -10 and 10?

Back

Distance = |10 - (-10)| = |10 + 10| = |20| = 20 units.
