Determine the constant of proportionality (k) for the table and write the relationship between x and y?

Multiple Choice

Determine the constant of proportionality (k) for the table and write the relationship between x and y?

• k = 1/4

  y = 1/4x

• k = 4

  y = 1/4x

• k = 4

  y = 4x

• k = 1/4

  y = 4x

The values of x and y are proportional. ​Determine the constant of proportionality (k) and find the missing values.
