Question
Suppose that C and D are points on the number line.
If
and D lies at ,
where could C be located?
Solution
The distance between points C and D is given as 14 units. Point D is located at -17 on the number line.
There are two possible locations for point C:
-
To the left of D: If C is to the left of D, we subtract the distance from the location of D. So, C would be at -17 - 14 = -31.
-
To the right of D: If C is to the right of D, we add the distance to the location of D. So, C would be at -17 + 14 = -3.
So, the possible locations for point C are -31 and -3 on the number line.
