Question

find the distance between points d and h.
d
h
-100
-60
-20
20
60
100

Explanation:

Step1: Identify the coordinates

The coordinate of point D is -80 and the coordinate of point H is 40.

Step2: Use distance formula

The distance $d$ between two points on a number - line is $d=\vert x_2 - x_1\vert$. Here, $x_1=-80$ and $x_2 = 40$. So $d=\vert40-(-80)\vert$.

Step3: Simplify the expression

$d=\vert40 + 80\vert=\vert120\vert = 120$.

Answer:

120
