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.

Use Pathagorean Theorem to find the distance between each pair of points, C(-10,2), D(-7,6)
-------------------------
d = sqrt[(6-2)^2 + (-7-10)]
---
d = sqrt[4^2 + 17^2]
---
d = 17.464...

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

The distance formula is: D = sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2+%2B+%28y%5B1%5D-y%5B2%5D%29%5E2%29
Therefore, D = sqrt%28%28-10--7%29%5E2+%2B+%282-6%29%5E2%29 -----> D = sqrt%28%283%5E2%29+%2B+%284%5E2%29%29
D = sqrt%289+%2B+16%29-----> D = sqrt%2825%29 -----> highlight_green%28D+=+5%29
