Answer:
rate of change is 4.
Step-by-step explanation:
rate of change is the slope, so, pick any two relations given to us in the table.
(-3, -14) and (-1, -6).
slope = y2 - y1/ x2 - x1
slope = -6 - (-14)/-1-(-3)
slope = 8/2 = 4.
the rate of change is 4.
6.932635
^ This is the tenths place.
Since the number after it is less than 5, we round down.
So we round to:
6.9
(-1,3) (2,-3) (-5, -1) (-6,-4)
