(-6,0), (-3,-1), (0,-,-3) what is the rate of change for the set of ordered pairs?

For the x: -6, -3, 0, 3

The rate of change is 3, as it adds 3 each time.

-6 + 3 = -3
-3 + 3 = 0
0 + 3 = 3
etc.

For the y: 0, -1, -2, -3

The rate of change is -1, as it subtracts 1 each time.

0 - 1 = -1
-1 - 1 = -2
-2 - 1 = -3
etc.

Rate of change: 
x is +3
y is -1

hope this helps
