First we are going to see if the relationship is proportional or not.
Let us calculate 2 ratios with two pairs to see if there is a constant of proportionality
10/1 = 10
8/2= 4
Since the ratios are not the same this relationship is not proportional.
From the information we can deduce that each minute the distance is reduced 2 blocks. Then, at the beginning Caleb was 12 blocks from home and he is walking at a rate of -2 blocks per minute.
- Since the relationship is not proportional we can not write an equation of the form y=k*x.
