Please help urgent !!!!!!!!


for each equation, determine whether x and y are directly proportional (that is, if the equation shows direct variation).

if so, then find the constant of proportionality (the constant of variation).


(a) 5/4 x = y


o proportional

constant of proportionality: k =

o not proportional


(b) y = -x


o proportional
constant of proportionality: k =

o not proportional
