Adjacent figure is a vertical number line, representing integers. Observe it and locate the following points:

(a) If point D is + 8, then which point is − 8?

(b) Is point G a negative integer or a positive integer?

(c) Write integers for points B and E.

(d) Which point marked on this number line has the least value?

(e) Arrange all the points in decreasing order of value.

there are two point point a is on a mountain which is 5700 m above see level and the point b is in a mine which is 39600m below sea level. find the vertical distance between a and b
