Question 639003
Remember that the two generic points are (x1, y1) and (x2, y2)


So (x1, y1) = (5, 5), which means x1=5 and y1=5
and (x2, y2) = (9, 2), which means x2=9 and y2=2


So in short, x1=5, y1=5, x2=9, and y2=2.


-------------------


Now plug all this into the distance formula


d = sqrt((x2-x1)^2+(y2-y1)^2)



d = sqrt((9-5)^2+(2-5)^2)



d = sqrt((4)^2+(-3)^2)



d = sqrt(16+9)



d = sqrt(25)



d = 5



So exact distance between the two points is  <font color="red">5</font>  units.
