## 321drew123 Group Title 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. one year ago one year ago

Ever consider you shouldn't be in accelerated honors geometry?

2. 321drew123 Group Title

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

3. estudier Group Title

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

4. yummydum Group Title

okay so you need to use the distance formula to find the distance between two points :) $d=\sqrt {(y_2-y_1)+(x_2-x_1)}$

estudier? What?

6. Lukecrayonz Group Title

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

7. yummydum Group Title

so using that you would get $L=\sqrt{(-11+1)+(-3-11)}$

8. 321drew123 Group Title

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.

9. Lukecrayonz Group Title

No, Yummy, this is the correct way.

10. 321drew123 Group Title

yummydum, thats the distance from an endpoint to the point, not the line.

11. yummydum Group Title

okay well go with what sire crayon has to saay

12. Lukecrayonz Group Title

You're finding a farther distance than needed

13. yummydum Group Title

i was getting to that

14. 321drew123 Group Title

yeah

18. Lukecrayonz Group Title

@yummydum your distance was 12.17, much farther than the actual distance.

19. 321drew123 Group Title

estudier that is not how i remember us learning it in school, we learned a shorter way

20. estudier Group Title

It is short, they are just explaining everything in great detail.

21. yummydum Group Title

again...that wasnt my final answer i was getting to the point...but i see uve got this covered

22. Lukecrayonz Group Title

estudier that makes it look very confusing :P

Ok i think i understand it now. Thanks Luke
