The form of the equation of a line in slope intercept form is y=mx+b, where m is the slope and b is the y intercept. The first step is to find the slope of a line. Since it goes down 3 units for every 2 it moves to the right, it has a slope of -3/2. The y intercept is also obviously at (0,3). Therefore, the equation of this line is y=-3/2x+3.
