when y varies inversely as x we can write$y=\frac{k}{x}$

5. anonymous

just put the values of x and y

6. anonymous

so 5=k/-1?

7. anonymous

but what that mean? y varies inversely as x that means as x increases y will decrease...and when x decreases y will increase

8. anonymous

ok....?

and yeah k=-5
