Hi, there--

THE PROBLEM:
Find the distance from point (1, 2) to point (7, 6) to the nearest tenth of a unit.

A SOLUTION:
Let P(1,2) and Q(7,6) be two points. The the distance formula give the distance D between them.



Substitute the x- and y-values into the formula.


Simplify.




The  is the exact distance between these two points. 
Use a calculator to get an approximation to one decimal place.

The distance is approximately 7.2 units.


Hope this helps! Feel free to email if you have any questions about the solution.

Good luck with your math,
