Solution

## The correct option is A i. 2, ii. -4, iii. left, iv. rightOn a number line, if we are moving towards right then its considered as positive and moving towards left is considered as negative. i. Moving 4 numbers to the right of -2 means -2 + 4 = 2 ii. Moving 5 numbers to the left of 1 means 1 - 5 = -4 iii. If we are at -8 on the number line and we have to reach -13 then this means -8 + x = -13 where x is the distance to be moved either in left or right direction. ⇒ x = -13 + 8 = -5 ⇒ We have to move 5 numbers towards left (since -5 has a negative sign) to reach -13. iv. If we are at -6 on the number line and we have to reach -1 then this means -6 + x = -1 where x is the distance to be moved either in left or right direction. ⇒ x = -1 + 6 = 5. ⇒ We have to move 5 numbers towards right (since 5 has a positive sign) to reach -1.
