suppose y varies directly with x . If y=-3 when x=5 , find y when x=-1

OpenStudy (blondisaurus):

The equations you'll be using is y=kx. Sorry a few mistakes had to reedit that

OpenStudy (anonymous):

so would it be 3/5 ?

OpenStudy (blondisaurus):

-3/5 Yes or -0.6

OpenStudy (anonymous):

it wasn't right

OpenStudy (blondisaurus):

Thats because 3/5 isnt the final answer

OpenStudy (blondisaurus):

You plug in k and the new x (which is -1) and solve for y
