what is the answer for this

Question

what is the length of (-9,-4) and (-2,-6)

Answer 1

For two points (x1,y1) and (x2,y2) the distance formula would determine the length of a line segment between those two points:

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

here (x1,y1) = (-9,-4) and (x2,y2) = (-2,-6)

applying the distance formula:

sqrt((-2--9)^2 + (-6--4)^2) = sqrt(53) = 7.28

Answer 2

-9-(-7),=7

-4-(-6)=-2

a^2+b^2=c^2

49-4=45^.5=6.708....
