## coolaidd 2 years ago If y varies inversely as x, find the constant of variation if y = 5 when x = -1.

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

5. sritama

just put the values of x and y

6. coolaidd

so 5=k/-1?

7. mukushla

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. coolaidd

ok....?

9. mukushla

and yeah k=-5
