find the coordinate of the foot of the perpendicular from the point (2,3) on the line x+y=11

Question

tamtoan · Answer

if you are given a slope of a line, what is the slope of perpendicular line?

anonymous · Answer

-1 ?

tamtoan · Answer

ok..then you will have one equation...let's say the 2 lines intersect at point (x1,y1) ..then write equation of slope of perpendicular line... remember the point (x1,y1) is also on the original line too
so you will have a system of 2 equations with 2 variables, you can solve for that

anonymous · Answer

Actually the slope of the perpendicular line is equal to -1 over the slope w/c is given.  I cas her you are correct @Devanshi

anonymous · Answer

let coordinate be (x,y)
 x + y = 11
and (y - 3)/(x - 2) =  1
 m1 m2  = -1
x = 5
y = 6

devanshi, what is the slope of the line x + y = 11 ?

anonymous · Answer

1

tamtoan · Answer

devanshi , slope is in the form ,,,y = mx + b , are you sure slope of x + y = 11 is 1 ?

anonymous · Answer

did you get my explanation ?

anonymous · Answer

I did
Thanks :)
