Answer:

C) 3/4

Step-by-step explanation:

The equation for rate of change is (y2-y1)÷(x2-x1) These numbers come from two ordered pairs off the table of your choice (x1,y1) (x2,y2). I used the first two rows of the table so my two order pairs are (-8,-12)=(x1,y1) and (8,0)=(x2,y2) Next i plugged the ordered pairs into the equation:

0-(-12) ÷ 8-(-8)

In both the numerator(top) and the denominator(bottom) are subtracting a negative which is the same as adding so the fraction is 12/16. This can be further simplified by dividing the top and bottom by 4 to get the final answer of 3/4
