direct variation y = kx <-- direct variation equation where k is constant of variation so plug in x and y value solve for k

2. anonymous

it would be c

3. anonymous

Thank you both!

4. Nnesha

so what you got ?

5. anonymous

:-)

15. Nnesha

see i told you and thanks for telling me

answer without explanation = no way! keep that in mind now replace y by -5 and x by -15 $\huge\rm -5 = k(-15)$ solve for k
