1.4
2.3
step-by-step explanation:
the formula for the constant of variation is
y= kx
divide each side by x
y/x =kx/x
y/x =k
we know a and y
1. y/x = k
4/1 =4
check the other values to make sure they are the same
8/2 = 4 12/3 =4 and 16/4 =4
the constant of variation is 4
2. y/x = k
3/1 =3
check the other values to make sure they are the same
6/2 = 3 9/3 =3 and 12/4 =3
the constant of variation is 3
