For this case, we have that by definition, the distance between two points any A and B will be the absolute value of the subtraction of their coordinates in the order that is preferred. (the distances can not be negative)
So:
We find the distance from A to a point x located at 0. ENtonces:
[tex]| -8-0 | = | -8 | = 8[/tex]
Now we add the distance from x to C. From point x (located at zero) to point C there are 5 spaces, then:
[tex]8 + 5 = 13[/tex]
Thus, the distance from A to C is 13
Answer:
13
