Answer
The distance length between point a at 3 to point b at 7 is 4 units.
Step-by-step Explanation
The question wants us to find the distance between a point a located at 3 and another point b located at 7.
To solve this, we would visualize the question using the number line. The number line is one horizontal line whose markings represent integer numbers (whole numbers). So, if we want to find the distance from point 3 to point 7 on the number line, we simply move along the number line from 3 to 7.
To move this way we take it in steps of 1
3 to 4 (1 unit)
4 to 5 (1 unit)
5 to 6 (1 unit)
6 to 7 (1 unit)
So,
3 to 7 (1+1+1+1 = 4 units)
It is easy to see that the distance from point a at 3 to point b at 7 is simply
7 - 3 = 4
Hence, the distance length between point a at 3 to point b at 7 is 4 units.
Hope this Helps!!!
