The line equation in slope-intercept form is , where m is the slope and b is

the y-intercept.

First find the y-intercept value.

                       (Substitute for m)

                 (Substitute 2, for x, y)

                         (Multiply: )

\

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

        (Add 1 to each side)

Apply commutative property of addition: a + b = b + a.

                 (Apply Additive inverse property: )

                       (Apply Additive identity property: )

                             (Add: )

Substitute for m and 2 for b in the Slope-intercept form equation.

The line equation in slope-intercept form is .
