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.

No? This is actually the only topic we've covered that I don't understand. I feel like that was an insult...

Slope of line L gives you slope of perpendicular.....

okay so you need to use the distance formula to find the distance between two points :) \[d=\sqrt {(y_2y_1)+(x_2x_1)}\]

Find midpoint between the two points on the given line, use distance formula to find the distance between the given point and the midpoint.

so using that you would get \[L=\sqrt{(11+1)+(311)}\]

All 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.
