Question
Find the equation of line cutting an intercept at
−
2
on the
y
−
axis and equally inclined to the axes
Open in App
Solution
Given
y
−
intercept
(
c
)
=
−
2
and the line is equally inclined to the axis i.e., same angle to the x-axis and y-axis(say)
=
θ
but the angle between the axes is
90
∘
2
θ
=
90
∘
⇒
θ
=
45
∘
As slope and
y
−
intercept are given.
Equation of line is
y
=
m
x
+
c
c
=
−
2
and
m
=
tan
45
∘
as line is equally inclined to the axes.
c
=
−
2
and
m
=
1
Equation of line is
y
=
