Internal or external
x=mx2+nx1m+nx = \frac{mx_2 + nx_1}{m + n}x=m+nmx2+nx1
y=my2+ny1m+ny = \frac{my_2 + ny_1}{m + n}y=m+nmy2+ny1
x=mx2−nx1m−nx = \frac{mx_2 - nx_1}{m - n}x=m−nmx2−nx1
y=my2−ny1m−ny = \frac{my_2 - ny_1}{m - n}y=m−nmy2−ny1
When m=nm = nm=n
x=x1+x22x = \frac{x_1 + x_2}{2}x=2x1+x2
y=y1+y22y = \frac{y_1 + y_2}{2}y=2y1+y2
Internal uses + (both numerator and denominator); external uses - (both)
