Suppose you have a line ` with corresponding equation ax + by + c = 0; also suppose you have points
(s, t) and (u, v) not on `. Write the parameterization of the line m passing through (s, t) and (u, v)
and use it to show that (s, t) and (u, v) are on opposite sides of ` if and only if there is a rational λ
between 0 and 1 so that the parameterization of m at λ is on the line `
