Point slope form Example

Find the equation of the line joining the points (3, 6) and (2, -5). x₁ = 3, y₁ = 6, x₂ = 2, y₂ = -5 Substitute in the formula as -1(y - 6) = -11(x - 3) 1(y - 6) = 11(x - 3) y - 6 = 11x - 33 Equation = 11x - 33 - y + 6 Equation of the Line = 11x - y - 27 = 0 The above example will clearly illustrates how to calculate the Two Point form manually.
