Given point is   and slope(m) = .

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) = .

                  (Substitute 0 for ,12 for and m = )

Rewrite in slope - intercept form.

                 (Apply additive identity property: )

            (Apply distributive property: )

                   (Multiply: )

                        (Divide: )

The equation of the line is  .
