Question

What is the rate of change for the linear relationship modeled in the table?

x y
-1 10
1 9
3 8
5 7
A -1/2
B 0
C 1/2
D 2​

Answer 1

A.-1/2 is the answer due to the fact that the rate of change is y/x. The rate at which the y values are changing is -1, and the rate at which the d values are changing is +2. Put them together, -1/2. Hope this helps

Answer 2

Use the first and lay set of x,y values.

Rate of change is change in y/ change in x:

7-10 / 5- -1 = -3/6 = -1/2

The answer is A.-1/2
