Final answer:
The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. To find it, calculate the ratio between the y-values and x-values.
Step-by-step explanation:
The constant of proportionality represents the ratio between the dependent and independent variables in a proportional relationship. To find the constant of proportionality for the table of values, we need to calculate the ratio between the y-values and x-values. For example, if the table has values (x, y) = (2, 7) and (4, 14), the ratio would be 7/2 = 3.5. The constant of proportionality for the table is the same ratio for all the values.
In this case, the correct answer would be (b) 3.5.
