Find the unit rate for each of the following tables

First table's unit rate is -1.6

Second table's unit rate is  3.5

Step-by-step explanation:

First table:

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:

and the rate is constant for any pair of (x, y) values of the table.

So the unit rate is: 7/2 = 3.5

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
