Question

if A= (1,-2), b= (-2,3), c= (2,-5) are the vertices of a triangle, find the equation of altitude AM​

Answer 1

Step-by-step explanation:

let AM is the altitude drawn from A to BC

M is the midpoint of BC

M=(-2+2/2;3-5/2)

M=( 0,-1)

equation of AM is

slope of the line AM is -1+2/0-1 [y2-y1/x2-x1]

slope m =-1

equation is.

(y-y1)=m(x-x1)

[y-(-2)]=(-1)(x-1)

y+2=-x+1

x+y+1=0 is the equation of AM
