Alright, freshman accelerated honors geometry problem. I need ton of help. How do you find the distance between a point and a line?
Ex:
Line L contains points (11,1) and (3,11). Point P has coordinates (1,1).
HELP.

Best ResponseYou've already chosen the best response.1okay so you need to use the distance formula to find the distance between two points :) \[d=\sqrt {(y_2y_1)+(x_2x_1)}\]

Best ResponseYou've already chosen the best response.1so using that you would get \[L=\sqrt{(11+1)+(311)}\]

Best ResponseYou've already chosen the best response.0All I know is that I need to find the point the coordinate is closest to on the line, then use the slope to find the length of the line its used to.
