The line equation in slope-intercept form is ,

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

Calculate the slope,

m = 

    =                                (Substitute )

    =                                  (Subtract:)­­

The line crosses the y-axis at (0, 3). So the y-intercept is 3.

Substitute m = and b = 3 in slope-intercept form line equation.

The slope-intercept form of the line equation is .
