Question

Find the equation of the line passing through the point ( 1, 2 ) and having inclination 60°

Answer 1

Answer:

Given,

Inclination of a straight line is 60

o

So, the slope =tan60

o

=

3

=m

And, the equation of line passes through the point (0,−3)=(x

1

,y

1

)

Hence, the equation of line given by

y−y

1

=m(x−x

1

)

y+3=

3

(x−0)

y+3=

3

x

3

x−y−3=0

Thus, the line equation is

3

x−y−3=0 .
