Answer: 1/4
==================================================
Step-by-step explanation:
Pick any two rows from the table to form (x,y) points
I'll select the first two rows.
(x1,y1) = (-4,-3) from row 1
(x2,y2) = (0,-2) from row 2
Plug those values into the slope formula
m = (y2-y1)/(x2-x1)
m = (-2-(-3))/(0-(-4))
m = (-2+3)/(0+4)
m = 1/4
The slope is 1/4, which is also the rate of change.
