What is a number line?
A number line is a depiction of a graded straight line that serves as an abstraction for real numbers, which are symbolized by the Number lines used in introductory mathematics.
It is generally accepted that a real number may be assigned to each point on a number line and that each real number can be assigned to a point.
Generally, the equation for the distance between two points is mathematically given as
[tex]d (P, Q) = \sqrt{ (x2 - x1)^2 + (y2 - y1) ^2}[/tex]
Therefore
[tex](P, Q) = \sqrt{ (6- ( -3)) ^2+ ( (-3)- (-3))^2 } \\\\ (P, Q)=9[/tex]
In conclusion
d (P, Q)=9
