Given point is   and slope(m) = 0.

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) = 0.

(Substitute 6 for ,5 for and m = 0)

Rewrite in slope - intercept form.

              (Product of two same signs is positive)

           (Apply distributive property: )

                         (Apply zero product property: )

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

              (Subtract 6 from  each side)

                    (Apply additive inverse property: )

                            (Apply additive identity property: , )

The equation of the line is  .
