The formula for slope-intercept form is y = mx + b. M being the slope and B being the y-intercept. The first thing I would do is find the slope. (y2-y1/x2-x1) The slope is -3/1 or -3. So now the equation looks like this: y = -3x + b Now to find the b. The y-intercept is the value of why when x is zero. In this case it is 2. So your answer is y = -3x + 2. Hope this helps!
