Answer:
First table's unit rate is -1.6
Second table's unit rate is 3.5
Explanation:
First table:
![\Delta y/\Delta x =(-16--8)/(10-5)= -8/5](https://img.qammunity.org/2021/formulas/mathematics/college/r4lgqbosty3cqno9frd4dvg8thp2sn3wut.png)
and this is constant for any pair of (x, y) values of the table.
So the unit rate is: -8/5 = -1.6
Second table:
![\Delta y/\Delta x =(21-7)/(6-2)=14/4=7/2](https://img.qammunity.org/2021/formulas/mathematics/college/bnepd1w4qbybe0qagsj5v82w469u4ux6f0.png)
and the rate is constant for any pair of (x, y) values of the table.
So the unit rate is: 7/2 = 3.5
