General Introduction
Given:
y
=
6
x
Compare to the standard equation form of
y
=
m
x
+
c
Where
m
is the gradient (slope)
Looking at the question we see that the gradient is 6.
This means that for 1 along on the x-axis the line has gone up 6 on the y-axis.
y
=
6
x
→

→
m

.
Building the equation of the perpendicular line
A line perpendicular to
y
=
m
x
+
c
has gradient
−
1
m
If
m
=
6
then
−

m
=
−

6
So the straight line perpendicular to that given has the equation
y
=

m
x

c
→
y

.
Determine the value of the constant
c
This line passes through the point
(

y
)
→
(

)
So by substitution
y

(

so the equation of the perpendicular line is:
