machine 1: formula for slope: [tex]\frac{y2- y1 }{x2 - x1} [/tex] for example : [tex] \frac{1.2 - 0.6}{2 - 1} = \frac{0.6}{1} = 0.6 \: is \: the \: slope[/tex] machine 2: [tex] \frac{rise}{run} [/tex] how many squares go up? how many squares go across until u touch the line? the slope is 1. [tex] \frac{1}{1} = 1[/tex]
