x y
10 27
11 a
12 11

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?

a = 2
a = 3
a = 19
a = 35​

Respuesta :

Answer:

a = 19

Step-by-step explanation:

If the rate of change is -8, subtract 8 from your y value of 27. And if 19 is correct, you should be able to subtract 8, and get 11 as the next number in the function, which you do, so 19 is the value of a.
