What is the constant of proportionality in this proportional relationship?
a) 4/5
b) 5/4
c) 4
d) 5

Answer 1

Answer:

a

Step-by-step explanation:

The equation of a proportional relationship is

y = kx ← k is the constant of proportionality

Divide both sides by x

$\frac{y}{x}$ = k

To find k use any ordered pair from the table

Using (2, $\frac{5}{2}$ ) , then

k = $\frac{2}{\frac{5}{2} }$ = 2 × $\frac{2}{5}$ = $\frac{4}{5}$
