### 1 Answer

If two lines are perpendicular, then the product of their slopes is -1.

We'll put the given equation of the line in the slope intercept form:

y = mx + n

y = -2x + 1

Comparing both equations, we'll get the slope m = -2.

The slope of the perpendicular line is m1 = 1/2

The equation of the line that is passing through the point (3,2) and it has the slope m1 = 1/2, is:

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

y - 2 = x/2 - 3/2

y = x/2 - 3/2 + 2

y = x/2 + 1/2

**The requested equation of the perpendicular line is y = x/2 + 1/2.**
