Consider the point(x,y):p2((x,y);(3,3))=(x3)2+(y+3)2The slope of corresponding line equals y+3x3. As a result, we have an equation:(x3)2+(y3)2=y+3x3\displaystyle \text{Consider the point(x,y):}\\ p^2((x,y);(3,-3)) = (x-3)^2 + (y+3)^2\\ \text{The slope of corresponding line equals $\frac{y+3}{x-3}$. As a result, we have an equation:}\\ (x-3)^2 + (y-3)^2=\frac{y+3}{x-3}
