How can you identify Direct variation using a table?
The values for the dependent variables must all be equal to the corresponding values of the independent variable, multiplied by the SAME constant. For example, if in the first row of the table, the dependent variable is 7.8 times the independent variable, the same factor must also apply in the other rows. Minor variations are acceptable; among other things, due to measurement errors.
