Question 13341
The formula to find the distance between two points is {{{D = sqrt((x2 - x1)^2 + (y2 - y1)^2)}}}...where (x1,y1) are the coordinates of the first point (in your case, (9,5)...and (x2,y2) are the coordinates of the second point (in your problem, (2,6). Plug your points into the equation to get:  {{{D = sqrt((2 - 9)^2 + (6 - 5)^2)}}}.  Subtract the numbers in the parentheses to get:  {{{D = sqrt((-7)^2 + (1)^2)}}}.  Square -7 and 1 to get:  {{{D = sqrt(49 + 1)}}}.  Add to get {{{D = sqrt(50)}}}.  Simplify the square root to get {{{D = 2sqrt(5)}}}.
