An 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.

Solution:

We use the concepts of positive and negative integers on a number line to locate the points based on the given statements.

(a) If point D is +8, point F represents -8, i.e 8 points below 0.
(b) Point G is a negative integer as its below 0.
(c) B = +4 and E = – 10
(d) Point E has the least value of -10.
(e) All the points are arranged in decreasing order as: D, C, B, A, O, H, G, F and E.
