Question

can someone help, If y varies directly as x, find the constant of variation if y = 5 when x = -0.1.

Answer 1

if y varies directly as x
then we can write y=kx where k is constant of variation
and k =y/x

Answer 2

here y=5 and x= -0.1
hope u will be able to find k

Answer 3

i am not sure exactly how this works in the first place

Answer 4

k = -5/0.1= -50
