Given the points (2.1) and (-4,-5) Find the point-slope form of the line.

  y = x - 1

Step-by-step explanation:

Use the Point-Slope form: y - y₁ = m(x - x₁)    where

Let (x₁, y₁) = (2, 1) and (x₂, y₂) = (-4, -5)

Point-Slope form:   y - 1 = 1(x - 2)

                               y - 1 =  x - 2      distributed 1 to (x - 2)

                                    y = x - 1       added 1 to both sides
