y -5, -10, 10, 5, 3 1/3
b. x -2, -1, 1, 2, 3
y -1 1/2, -4, 6, 3 1/2, 2 2/3
c. x -2, -1, 1, 2, 3
y -2 1/2, -5, 5, 2 1/2, 1 2/3
d. x 1, 2, 3, 4, 9
y 2, sqrt of 2 , 2sqrt of 3 over 2, 1, 2/3
e. In an inverse variation, what value will either variable never assume? why?

Hi
Find the constant of proportionality and the equation of variation where appropriate.
a. x -2, -1, 1, 2, 3
y -5, -10, 10, 5, 3 1/3 y = 10/x
c. x -2, -1, 1, 2, 3
y -2 1/2, -5, 5, 2 1/2, 1 2/3 y = 5/x
e. In an inverse variation, what value will either variable never assume? why?
that would be 0 ( x ≠ 0, cannot divide by zero and y≠ 0 as k ≠ 0)
