Math 10 Week 14

This week we learned how to find the length of of a line segment. This takes place in graphing. It is from one coordinate to another.

ex. Say the coordinates are x1 and y1 (2, -10) and (4,8) x2 and y2

To find the length of a line segment you need to use the formula of (x1-x2) ^2 + (y1-y2) ^2 = C^2 

(2-4)^2 + (-10 - 8)^2C^2


You are doing this step because of pythagoras

4 + 324 = C^2

\sqrt{328} = C^2

The length of the line segment is roughly 18.1
