Question 209525
The question says: Use Pathagorean Theorem to find the distance between each pair of points, C(-10,2), D(-7,6).

I have been looking over my notes and working very hard on this problem, but I just don't seem to get it.


The distance formula is: D = {{{sqrt((x[1]-x[2])^2 + (y[1]-y[2])^2)}}}

Therefore, D = {{{sqrt((-10--7)^2 + (2-6)^2)}}} -----> D = {{{sqrt((3^2) + (4^2))}}}

D = {{{sqrt(9 + 16)}}}-----> D = {{{sqrt(25)}}} -----> {{{highlight_green(D = 5)}}}
