Answer:
The constant of variation is 1.6.
Step-by-step explanation:
y = kx and x = 5 when y = 8 and k = the constant of variation.
8 = k*5
k = 8.5 = 1.6.
Answer:
8/5
Step-by-step explanation:
Plug in the point given into
y=kx.
The number you get for y will be your constant of variation, also know as constant of proportionality.
(x,y)=(5,8) implies 8=k(5)
So in solving that equation we just need to divide both sides by 5 giving us:
8/5=k.
