Answer 1

Answer:
I couldn't quite understand, but I tried...
The pairs that have the same constant of proportionality are (2,22), (7,77), and (9,99).

Explanation:

I found the constant of proportionality; I needed to divide each yy value by its corresponding xx value.

For the first pair (2,22), the constant of proportionality is:

22/2 = 11

For the second pair (7,77), the constant of proportionality is:

77/7 = 11

For the third pair (7,77), the constant of proportionality is:

77/7 = 11

For the fourth pair (24.5, 24.5), the constant of proportionality is:

24.5/24.5 = 1

For the fifth pair (9,99), the constant of proportionality is:

99/9 = 11

For the sixth pair (31.5, 31.5), the constant of proportionality is:

31.5/31.5 = 1
