The document provides the steps to solve a problem where two points (m,3) and (1,m) lie on a line with slope m, and m must be greater than 0. It uses the slope formula with the given points, multiplies both sides by (m-1) to remove it from the denominator, isolates m by adding m to both sides, and takes the square root of both sides to find the only possible value of m that satisfies the constraints.
