In order for the data in the table to represent a linear function with a rate of change
of -8, what must be the
value of a?
O a= 2
O a = 3
A
O a = 19
O a = 35

a = 19

If the rate of change is -8, everytime you do up for x you will minus 8. For example, x = 10 so y = 27 ; x=11 so y = 27-8 = 19 ; x = 12 so y = 19-8 = 11.

Therefore, when x is 11; y is 19

answer: it is 1: 47 pm

they would have to work 32 hours.
