The line equation in slope-intercept form is ,

where m is the slope and b is the y-intercept.

Calculate the slope,

m = 

    =                          (Substitute )

      =                                (Multiply: )

    =                                      (Add: )­­

     =                                        (Divide: )­­

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

Substitute m = 2 and b = -2 in slope-intercept form line equation.

                                  (Product of two different signs is negative)

The slope-intercept form of the line equation is .
