Have need help with my homework I’m so confused I can’t think

Answer 1

In the equation of a direct proportion in the form $y = kx$, the constant of proportionality is k, i.e. the number multiplying the independent variable. So, in you case, you have

$y = 5x \implies \text{constant of proportionality} = 5$

$y = \dfrac{10}{5}x = 2x \implies \text{constant of proportionality} = 2$

$y = \dfrac{5}{25}x = \dfrac{1}{5}x \implies \text{constant of proportionality} = \dfrac{1}{5}$

$y = \dfrac{1}{2}x \implies \text{constant of proportionality} = \dfrac{1}{2}$
