    2, 1 --3, -2 ------- 5,-1 slope = -1/5 y-1 = -1/5 (x-2)

    y=mx+b y=1 1=2(-1/5)+b 1=-2/5+b solve the equation b=find it out :)

    point slope form; but yes, that is a good way to determing the slope intercept form

    no; there is only one way to use the point slope form of a line. There are many ways describe the equation of a line. .... but only one way to describe it in point slope form....

    yes but their is y=mx+b and y-\[_{?}\]=m(x-\[_{?}\]

    the y intercept form and the point slope formula u can do it both ways

    "Choose the point-slope form of the equation": y - y1 = m(x-x1) ; where point is P(x1,y1). Now if you want to do this the long way..... then yes, try to fight thru the slope-intercept form to get to it. By the way, I have never really found a good use for the point-slope form, unless we are looking for the equation of a tangent line to the curve, then its pretty handy :)
