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

First find the slope of the line.

                                 (Substitute )

                                 (Apply additive inverse property: )

                                       (Apply additive identity property: )

                                          (Apply zero product property: )

Next find the y-intercept.

The line crosses the y-axis at (0, 2).

So, the y-intercept is 2.

Replace m with 0 and b with 2 in the equation .

y = 0 + 2                                         (Apply zero product property: )

y = 2                                               (Apply additive identity property: 2 + 0 = 2)

The slope-intercept form line equation is y = 2.
