Question

Suppose that y varies inversely with x, and y = 2 when x = 6. What is an equation for the inverse variation?
x = y/4
y = 12/x
y = 4x
y = x/12

Answer 1

Only one equation has a y that varies inversely with x, and that equation is also the only one that gives y = 2 when x = 6, try calculating the y-values for all by filling in x = 6.

Answer 2

Or in case of the first equation: fill in y = 2 and see if x = 6 comes out :)

Answer 3

okay thank you!

Answer 4

So did you find answer b? :)

Answer 5

yes :)
