Question

Dennis walks from (–5, –2) to (–5, 5) on the map. Which expression represents the distance that he walked? |-2| + |5| |-5 + 5| |-2| - |5| |-5| + |-5|

Answer 1

|-2| + |5|

Explanation:

Dennis walks from (–5, –2) to (–5, 5) on the map.

Point on the format (x,y). On the x-coordinate, he stayed at the same position, x = -5, so it does not enter the distance calculation.

On the y-coordinate, he went from -2 to 5, so the distance is of:

`d = 5 - (-2) = 5 + 2 = |5| + |2| = |5| + |-2| = 7`

So the correct option is |-2| + |5|
