slope = exchange in y, as x grows via one unit. technique: divide: exchange in y / exchange in x (the order would not matter different than that the two differences could be interior the comparable order. slope = ( a million/4 - a million/2 ) / (2/5 - 2/3) = (a million/4 - 2/4 ) / ( 6/15 - 10/15) = (-a million/4) / (-4/15) dividing via a fragment is the comparable as multiplying via the inverse of the fraction = (-a million/4)*(15/-4) slope = -15/-sixteen = 15/sixteen (minus divided via minus = + )
