Question

In her science classroom Jane noticed that the lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality.

Answer 1

Answer: C) 30.0 ounces

Step-by-step explanation:

Use one of the ordered pairs that are given to find the value of 'k', the CONSTANT of variation. This number will not change, hence the word 'constant'.

15 = k*6; dividing both sides by 6 we get k = 2.5; The equation used for the table is y = 2.5x

You can find any value now by using this formula.

y = 2.5*12

y = 30

Answer 2

30.0 ounces is correct.
