Answer:
1
Step-by-step explanation:
Please use parentheses around the coordinates of your points:
(1, 4); (0.5, 3.5), etc.
If we go from (0.5, 3.5) to (1, 4), x increases by 0.5 and y increases by 0.5.
Thus the slope is m = rise / run = 1/1 = 1.
This is the average rate of change for the sequence shown.
