Nope, you do not mean cumulative density function. I am sure.

@calculus regression minimises the total squared distance between realisations of $X$ and $Y$ to and the regression line, which goes through the origin in this case. I could have posed the question as I have a bunch of points $x_i$ and $y_i$ such that they have mean 0 and variance 1, the question would have still made sense.
