Question 171843
Find the distance between the given pair of points having the given coordinates:
a) 2 and 9
b) 2.65 and 6.11
c) -5 and 11
d) square root of 3 and square root of 7
e) -5.41 and -15.62
--------------------------
A point in cartesian coordinates must have an x and a y.  2 and 9 are not 2 points.  
An example of 2 points is (2,1) and (3,9).  The points are in the format (x,y)
