Find the distance of the point (3,0) from the line

y=1/2x+1

----------------------------------------

Do I have to find the equation for a line perpendicular to this one in order to solve the problem?

If so I think the slope of the line would be 2. So y=2x+b......but I don't know how to get the b value (or the y-intercept). And I'm just confused about how to set this problem up to solve for it.
