The line equation in slope-intercept form is ,

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

The slope of the line is  = .

The line crosses the y-axis at (0, – 8). So the y-intercept is – 8.

Substitute and b = – 8 in slope-intercept form equation.

                             (Product of two different signs is negative)

The slope-intercept form of the line equation is .
