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 )

                          (Product of two same signs is positive)

                          (Apply additive identity property: )

                            (Add: )

Next find the y-intercept.

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

the y-intercept is 2

Replace m with and b with 2 in the equation .

The slope-intercept form line equation is  .
