The line equation in slope-intercept form is ,

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

Calculate the slope,

m = 

    =                     (Substitute )

    =                              (Product of two same signs is positive)

    =                                  (Divide: )­­

The line crosses the y-axis at (0,24). So the y-intercept is 24.

Substitute m = and b = 24 in slope-intercept form line equation.

                         (Simplify)

The slope-intercept form of the line equation is .
