Question

In a direct variation, y is 4 when x is twelve. What is y when x equals six

Answer 1

so this is a direct variation: so if y=4 and x=12 then the numbers should show direct calculation. So if x=6. notice that the original x had 12, now it is 6 its been cut in half. Therefore y should equal to 2 since a half of 4 is 2. The answer is y=2.

Answer 2
