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, – 2). So the y-intercept is – 2.

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

                                (Simplify) \ \

The slope-intercept form of the line equation is .
