Question

I need help with number 9 thanks !

Answer 1

machine 1: formula for slope:

`(y2- y1 )/(x2 - x1)`
for example :

`(1.2 - 0.6)/(2 - 1) = (0.6)/(1) = 0.6 \: is \: the \: slope`
machine 2:

`(rise)/(run)`
how many squares go up? how many squares go across until u touch the line? the slope is 1.

`(1)/(1) = 1`
