what's the constant of proportionality
3 171
4 228
5 285
8 456
10 570
The constant of proportionality is 57.
To find the constant, divide the second number by the first number in each pair:
171 / 3 = 57
228 / 4 = 57
285 / 5 = 57
456 / 8 = 57
570 / 10 = 57
Therefore, the constant of proportionality is 57.
