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.
Ever consider you shouldn't be in accelerated honors geometry?
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 :) \[d=\sqrt {(y_2-y_1)+(x_2-x_1)}\]
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 \[L=\sqrt{(-11+1)+(-3-11)}\]
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.
No, Yummy, this is the correct way.
yummydum, thats the distance from an endpoint to the point, not the line.
okay well go with what sire crayon has to saay
You're finding a farther distance than needed

Explanation, answer is 8.6.
@yummydum your distance was 12.17, much farther than the actual distance.
estudier that is not how i remember us learning it in school, we learned a shorter way
It is short, they are just explaining everything in great detail.
again...that wasnt my final answer i was getting to the point...but i see uve got this covered
estudier that makes it look very confusing :P
Ok i think i understand it now. Thanks Luke
