Answer 2

Concept:

Distance between the points with coordinates as ' a ' and ' b ' is given by,

D = |b - a| = The numerical value of difference between two coordinates

Given:

The coordinates of the points P and Q on number line are -3 and 6 respectively.

Find:

We have to find the d(P,Q) i.e. the distance between the points P and Q on number line.

Solution:

Given that the coordinate of point P is -3

and the coordinate of point Q is 6.

So the distance between the points = d(P,Q) = |-3 - 6| = |-9| = 9 units.

Hence the distance between points P and Q with coordinates -3 and 6 respectively on number line is given by, d(P,Q) = 9 units.
