Please look in your text book for this problem Statement

Given point is   and slope(m) = 3.

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) = 3.

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

Rewrite in slope - intercept form.

           (Product of two same signs is positive)

         (Apply distributive property: )

             (Multiply: )

Apply addition property of equality: If a = b then a + c = b + c.

(Add 2 to  each side)

       (Apply additive inverse property: )

            (Apply additive identity property: )

                  (Add)

The equation of the line is  .
