anonymous · Answer

rate of change is the slope $$\frac{ \Delta y }{ \Delta x }$$.  for example in the first list, the slope is 1/3.  this means the y value changes 1/3 as fast as the x value does.  could represent anything.. if tommy runs 3x as fast as billy, and you calculated their distances at varies points along a race, you might get a similar looking plot

im still confused

anonymous · Answer

in the first list, the x-values are always 3 times as much as the y values.  x = 3y,  or y = 1/3 x.  your slope is then 1/3.
