For this case we have that the point-slope equation of a line is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It is the slope of the line

(x_ {0}, y_ {0}): It is a point through which the line passes

In this case we have to:

(x_ {0}, y_ {0}) :( 3,2)

Substituting in the equation we have:

y-2 = m (x-3)

Answer:

y-2 = m (x-3)

We just need to replace the value of the slope
