answer

Any line with gradient

1

3

will be perpendicular to the line

y

=

3

x

+

2

.

(it should have the form

y

=

1

3

x

+

b

, where b is an arbitrary number)

Step-by-step explanation:

To find the equation of perpendicular lines, find the reciprocal of the gradient (in this case

1

3

) and multiply it by

1

. To check, the gradient of the original line multiplied by the gradient of the new line should be equal to

1

.
