Question

8. The vertices of are A (2,1), B(6,-1) and a(4,11) Find the equation of
a straight line along the altitude from the vertex A​

Answer 1

Answer:

Slope of BC=

4−6

11+1

=−6

Since the line AD is perpendicular to the line BC, slope of AD=

6

1

∴ Equation of AD is y−y

1

=m(x−x

1

)

y−1=

6

1

(x−2)⇒ 6y−6=x−2

∴ Equation of the required straight line is x−6y+4=0
