Answer: -1/4

======================================================

Step-by-step explanation:

Pick any two rows from the table. I'll pick the first two rows

x = -8 and y = 10

x = 0 and y = 8

Those two rows form the points (x1,y1) = (-8,10) and (x2,y2) = (0,8)

They are then plugged into the slope formula to get...

m = (y2-y1)/(x2-x1)

m = (8-10)/(0-(-8))

m = (8-10)/(0+8)

m = -2/8

m = -1/4

The slope or rate of change is -1/4

---------

This means that each time x goes up by 4, y goes up by 1, since

slope = rise/run = -1/4

rise/run = -1/4

rise = -1 means we go down 1

run = 4 means we move to the right 4 units.
