Given point is   and slope(m) = 2.

Because you know the slope and a point on the line,

Use point - slope form to write an equation of the line.

Let =  and slope(m) = 2.

        (Substitute 3 for ,4 for and m = 2)

Rewrite in slope - intercept form.

               (Product of two same signs is positive)

            (Apply distributive property: )

                  (Multiply: )

       (Add 3 to each side)

             (Apply additive inverse property: )

                   (Apply additive identity property: )

                       (Add:  )

The equation of the line is  .
