Given points are

Next, find the slope.

Substitute 8 for y₂,  2 for y₁,3 for x₂, and 5 for x₁  in slope formula.

                              (Product of two same signs is positive)

                          (Add: )

                             (Add: )

                                  (Divide: )

You know the slope and a point on the line, so use point - slope form

with either given point to write an equation of line.

Choose

     (Substitute 2 for y₁, 5 for x₁ and )

                       (Product of two same signs is positive)

               (Apply distributive property: ) \ \

                   (Multiply: )

       (Subtract 2 from each side)

             (Apply additive inverse property: )

                    (Apply additive identity property: )

                                 (Subtract: )

The equation of line is .
