Answer 2

Option C is the correct option.
The number that is 7 to the left of -2 on the number line.

Given: -2 + (-7)

To find: The location of the above expression on number line.

Step by step explanation:

We will solve the above expression first,
⇒ -2 + (-7)
⇒ -2 -7                                  ........... ( '+' + '-' = '-' )
⇒ -9.
The final output of our expression is -9.

Option A The number that is 2 to the left of 7 on number line.
               i.e., 7 - 2 = 5.
                5 ≠ -9.
                ∴ This option is incorrect.

Option B The number that is 2 to the right of 7 on number line.
                i.e., 7 + 2 = 9.
                9 ≠ -9.
                ∴ This option is incorrect.

Option C The number that is 7 to the left of -2 on number line.
               i.e., - 2 - 7 = -9.
                -9 = -9.
                ∴ This option is correct.    (Correct answer)

Option D The number that is 7 to the right of -2 on number line.
               i.e., - 2 + 7 = 5.
                5 ≠ -9.
                ∴ This option is incorrect.
