Question

Find the distance between the points (-4, 6) and (8, -12).Round your solution to 2 decimal points.
can someone teach me how to solve this kind of problem. im very confused.

Answer 1

d=sqrt[{8-(-4)}^2+(-12-6)^2]
=sqrt(144+324)
=sqrt468
=21.63

Answer 2

thanks :)
so just so i have this in formula, is D=(x2-x1)^2+(y2-y1)^2
correct

Answer 3

D=sqrt(x2-x1)^2+(y2-y1)^2
ops forgot the sqrt

Answer 4

yes.

Answer 5

thanks for the help :)
