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 5 for , 9 for and m = )

Rewrite in slope - intercept form.

                 (Product of two same signs is positive)

         (Apply distributive property: )

                  (Multiply: )

                    (Divide: )

Apply subtraction property of equality: a = b then a c = b c.

         (Subtract 5 from each side)

               (Apply additive inverse property: )

                     (Apply additive identity property: )

                           (Subtract: )

The equation of the line is  .
