Answer:
Table 4
Step-by-step explanation:
Just imagine the data tables are graphs, just presented in a different form.
How do you calculate the slope in a graph? You divide the variation of Y by the variation of X. That's the same thing here. Let's look at each table, and calculate the slope based on the first 2 rows of each table:
Table 1:
S = (1 - -1)/(2-6)= 2/-4 = -2, not the one we want.
Table 2:
S = (8 - 4) / (0 - 2) = 4 / -2 = -2, not the one we want.
Table 3:
S = (4 - 5)/(-4 - -2) = -1 / -2 = 1/2, not the one we want.
Table 4:
S = (0 - 4)/(-2 - 0) = -4 / -2 = 2. Yes! That's the one!
