what's the constant of proportionality
3 45
6 90
8 120
11 165
The constant of proportionality in this scenario is 15. This can be found by dividing the second number by the first number in each pair:
45 / 3 = 15
90 / 6 = 15
120 / 8 = 15
165 / 11 = 15
Therefore, the constant of proportionality is 15.
