I am stumped on this problem can someone please explain?
Find the distance between the given points (3, 7) and (4, 15).
Thanks so much.

The distance formula is ..
given two points (x1,y1) and (x2,y2)
distance= sqrt ((x1x2)^2 + (y1y2)^2) 
Did I do this problem correctly?
D=sqrt[(15+7)^2+(4+3)^2]
D=sqrt[484+1]
D=sqrt 485
D ~22.023.
Is this answer correct? 
yes.
