Question

Witch table has the constant of proportionality between y and x of 8/5

table 1 table 2 table 3
4 32/5 2 14/5 5 20/3
10 16 6 42/5 9 12
11 88/5 20 28 12 16

Answer 1

Table 1

Explanation:

y = (8/5)x

32/5 = 8/5 × 4

32/5 = 32/5

16 = 32/5 × 10

16 = 16

88/5 = 8/5 × 11

88/5 = 88/5

Answer 2

Table 1

Explanation:

Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.

Table 1:

4 32/5

10 16

11 88/5

Let's find the constant of proportionality for each row:

R1: (32/5) / 4 = 8/5

R2: 16/10 = 8/5

R3: (88/5) / 11 = 8/5

Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.

If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.

Hope this helps!
