The number $5$5 is plotted on the number line below.

Find the value of $5+9$5+9.

A horizontal number line marked from -5 to 20. It is marked with major ticks at every 5-unit interval, specifically at -5, 0, 5, 10, 15, and 20, which are labeled accordingly. Minor ticks represent individual units and are placed at each integer between the major ticks. A filled diamond shape indicates the position of

5

on the number line. The position of the number was determined through analysis of the number line, as its exact location was not explicitly provided.

Outcomes

NC.6.NS.9

Apply and extend previous understandings of addition and subtraction. a. Understand additive inverses when adding and subtracting integers.• Describe situations in which opposite quantities combine to make 0.• Understand � + � as the number located a distance q from p, in the positive or negative direction depending on the sign of q. Show that a number and its additive inverse create a zero pair.• Understand subtraction of integers as adding the additive inverse, � − � = � + (– �). Show that the distance between two integers on the number line is the absolute value of their difference.• Use models to add and subtract integers from -20 to 20 and describe real-world contexts using sums and differences.
