people use the "distance formula"
\[ d = \sqrt{ (x_2 - x_1)^2 + (y_2 - y_1)^2 } \]
does that ring any bells?

the distance formula is really the pythagorean theorem
\[ x^2 + y^2 = c^2 \]
OpenStudy (chycora):
yes but were do rthe numbers go
OpenStudy (phi):
do you know how to plot points ?
OpenStudy (chycora):
yes
OpenStudy (phi):
ok, here is a rough sketch of your two points (-2, -3) and (-6, -5)|dw:1431025668942:dw|
