Direct Variations....

OpenStudy (anonymous):

y varies directly as x. If y = 6 when x = 3, find y when x = -33. Y=?

OpenStudy (anonymous):

y=kx and solve as before, theyre just changing up the wording of the question

OpenStudy (anonymous):

it could be written as (3,6) and (-33,y)

OpenStudy (anonymous):

so y=?

OpenStudy (anonymous):

y=kx -> 6=3k -> k=2

OpenStudy (anonymous):

y=2x -> x=-33 so y=-66
