Answer 1

9514 1404 393

Answer:

9/8

Explanation:

The equation of a proportional relationship is ...

y = kx

The constant of proportionality, k, can be found from ...

k = y/x . . . . . above equation divided by x

Using the given points, we find the constant of proportionality to be ...

k = (3/4)/(2/3) = (3/4)(3/2) = 9/8

The constant of proportionality is 9/8.
