Which appears to be the solution to the system of equations shown in the graph? (–2, 6) (–1, 5) (5, –1) (6, –2)

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

answer: -1

step-by-step explanation:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

false

inverse variation is not exponential
