Answer:


y = -(1)/(3)x + 4

Explanation:

Required

Equation of line

passes through
(6,2)

In an equation of the form
y =mx + b; the slope is
m

So, by comparison;

The slope of
y = 3x + 1 is:
m =3

From the question, we understand that the required equation is perpendicular to
y = 3x + 1

This means that its slope is:


m_2 =-(1)/(m)

So, we have:


m_2 =-(1)/(3)

The line equation is:


y = m_2(x - x_1) + y_1

Where:


(x_1,y_1) = (6,2)

So, we have:


y = -(1)/(3)(x - 6) + 2


y = -(1)/(3)x + 2 + 2


y = -(1)/(3)x + 4
