Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. For a point $(x,y)$ on the parabola we have that, $$d^2=(y-0)^2+\left(x-\frac32\right)^2=y^2+x^2-3x+\frac94=x^2-x+\frac94$$, and the minimum is attained for $x=\frac12$ thus at the point $(\frac12,1)$ and therefore, Given a point $P=\left(\frac{y^2}2,y\right)$ of your parabola, consider the line segment joining $P$ to $C=\left(\frac32,0\right)$. via m1 = (y2-y1)/(x2-x1).
