Question

find equation of horizontal line intercepting y axis 3 units above origin​

Answer 1

answer : We have,

tanθ=m=

2

1

Since, the line intersecting the y−axis at a distance of 3 units above the origin, it means y=3 and x=0.

So, the point (0,3)

We know that the equation of the line

y−y

1

=m(x−x

1

)

Therefore,

y−3=

2

1

(x−0)

2(y−3)=x

2y−6=x

x−2y+6=0

Hence, this is the answer.
